Factors are the numbers that are multiplied together to obtain a product. For example: The product of 6 × 7 = 42. It means that the numbers 6 and 7 are factors of 42.
In math, a factor pair is defined as a set of two factors, which, when multiplied together, give a particular product. In other words, it is a set of two numbers we multiply to get a product. For instance, in the multiplication statement, 6 × 7 = 42, 6 and 7 is one of the factor pair that gives us the product 42. In other words, 42 is the product o...
An integer is a whole number(not in fractional form) that can be positive, negative or 0. For example: -3, -10, 0, 18 etc. 1. Positive Integers Factor pairs of positive integers are the pairs of integers whose product will be the integer. For example: Factors of 12 are 1, 2, 3, 4, 6, and 12. We can write 12 = 1 × 12; 2 × 6; 3 × 4 So, the factor of ...
Fractions are the numbers that can be represented in the form of pq where p is the numerator and q is the denominator. For example: 35, 1115etc. Finding the factors of the fractions is the same as finding the factors of a whole number. For example: In the fraction 35, factors of 3 are 1, 3 and factors of 5 are 1, 5. So, the factors of 35 are 1, 3,1...
A decimal number is a number whose whole number part and the fractional part is separated by a decimal point. For example: 1.2, 3.456, 5.28 etc For example: For the decimal 1.2. Factors of 1.2 are 1, 2, 3, 4, 6, 12, 0.1, 0.2, 0.3, 0.4, 0.6, 1.2. The factor pairs of 1.2 are (1, 1.2); (2, 0.6); (3, 0.4); (4, 0.3); (6, 0.2); (12, 0.1).
An algebraic expression is an expression that is made up of variables and constants along with the algebraic operations like addition, subtraction etc. The factors of an algebraic expression can be formed by either splitting the middle term or finding the HCF. Example 1: For the expression 2 x+ 6 2 x + 6 = 2 (x+ 3) Factors of 2 x + 6 are 1, 2, (x +...
