In the division method, the factors of 3 are found by dividing the number 3 by the integer numbers. If the integer divides 3 exactly, then the integer is a factor of 3. Now, divide the number 3 by 1 and then continue with the numbers 2 and 3. 3/1 = 3 (Factor is 1 and Remainder is 0)

Aug 16, 2024 · The factors of 3 are the numbers that can be multiplied together to result in 3. Since 3 is a prime number, it has only two distinct factors: 1 and 3. This means that the only whole numbers that divide 3 evenly, without leaving a remainder, are 1 and 3. In other words, 1 multiplied by 3 equals 3 (1 * 3 = 3).
Solution: To find out the time taken to climb one hill, we will divide 3 by 3, that is, \ (\frac {3} {3}\) = 1 [as (1, 3) is a factor pair of 3] As a result, Ingrid spends one hour climbing each hill. Example 2: Find the common factors of 17 and 3. Solution: The factors of 17: 1 and 17. The factors of 3: 1 and 3.
- Yes, 1 is a factor of 3. This is because the number 1 divides 3 exactly, that is, it leaves 0 as the remainder. So, 1 is a factor of 3. Also, 1 is...
- 3 is not a composite number as it has exactly two factors. The factors of 3 are 1 and 3. This suggests that it is a prime number.
- The factors of 3 are 1 and 3.So, the smallest factor of 3 is 1, and the greatest factor is 3 itself.
- The factors of 3 are 1 and 3. Hence, the sum of all the factors of 3 is = 1 + 3= 4Hence, the sum is 4.
- The factors of 3 are 1, 3. So, 3 has two factors.

A Prime Number is: When it can be made by multiplying other whole numbers it is a Composite Number, like this: (The first few prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19 and 23, and we have a prime number chartif you need more.)
Here are some examples: It is neater to show repeated numbers using exponents: 1. Without exponents: 2 × 2 × 3 2. With exponents: 22× 3
We just did factorization by starting at the smallest prime and working upwards. But sometimes it is easier to break a number down into any factorswe can ... then work those factor down to primes.
A "Factor Tree" can help: find any factorsof the number, then the factors of those numbers, etc, until we can't factor any more.
A prime number can only be divided by 1 or itself, so it cannot be factored any further! Every other whole number can be broken down into prime number factors. This idea can be very useful when working with big numbers, such as in Cryptography.
Cryptographyis the study of secret codes. Prime Factorization is important to people who try to make (or break) secret codes based on numbers. That is because factoring very large numbers is very hard, and can take computers a long time to do.
And here is another thing: There is only one (unique!) set of prime factors for any number. This idea is so important it is called the Fundamental Theorem of Arithmetic.
OK, we have one more method ... use our Prime Factorization Toolthat can work out the prime factors for numbers up to 9007199254740991.
Jan 13, 2023 · So now we can stop since we have reached only prime numbers. So the prime factorization of 126 is: 126 = 2 x 3 x 3 x 7. = 2 x 9 x 7. = 2 x 63. = 126. We found one prime factor at a time, first the 2, then the 7, then the 3’s: 126 = 2 ×32 × 7. We’ll see more examples as we go.
Factors of a 3 are the numbers which on divide 3 and gives the remainder zero. Factors of 3 are 1 and 3 only. Note that -1 × -3 = 3. (-1, -3) are also factors, as a product of any two negative numbers gives a positive number.

If you can divide a number A by a number B, without remainder, we say that B is a factor (or divisor) of A, and that A is a multiple of B. We often write B|A, where the vertical bar simply means “divides”. For example, 7 × 3 = 21, so 7 is a factor multiple of 21. Similarly, 21 is a multiple factor of 7, and we can write 7|21.
