Steps to find factors of 38 in pair

Example: Find factors of 38 in pair

Factor Pair Pair Factorization
1 and 38 1 x 38 = 38
2 and 19 2 x 19 = 38

Since the product of two negative numbers gives a positive number, the product of the negative values of both the numbers in a pair factor will also give 38. They are called negative pair factors.

Hence, the negative pairs of 38 would be ( -1 , -38 ) .

What does factor pairs in mathematics mean?

In mathematics, factor pair of a number are all those possible combination which when multiplied together give the original number in return. Every natural number is a product of atleast one factor pair. Eg- Factors of 38 are 1 , 2 , 19 , 38. So, factors of 38 in pair are (1,38), (2,19).

What is the definition of factors?

In mathematics, factors are number, algebraic expressions which when multiplied together produce desired product. A factor of a number can be positive or negative.

Properties of Factors

  • Each number is a factor of itself. Eg. 38 is a factor of itself.
  • Every number other than 1 has at least two factors, namely the number itself and 1.
  • Every factor of a number is an exact divisor of that number, example 1, 2, 19, 38 are exact divisors of 38.
  • 1 is a factor of every number. Eg. 1 is a factor of 38.
  • Every number is a factor of zero (0), since 38 x 0 = 0.

Steps to find Factors of 38

  • Step 1. Find all the numbers that would divide 38 without leaving any remainder. Starting with the number 1 upto 19 (half of 38). The number 1 and the number itself are always factors of the given number.
    38 ÷ 1 : Remainder = 0
    38 ÷ 2 : Remainder = 0
    38 ÷ 19 : Remainder = 0
    38 ÷ 38 : Remainder = 0

Hence, Factors of 38 are 1, 2, 19, and 38
