Steps to find factors of 51 in pair

Example: Find factors of 51 in pair

Factor Pair Pair Factorization
1 and 51 1 x 51 = 51
3 and 17 3 x 17 = 51

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 51. They are called negative pair factors.

Hence, the negative pairs of 51 would be ( -1 , -51 ) .

Introduction to factor pairs

Factor pair in mathematics is defined as all factors of a given number which when written in pair and multiplied gives the original number. Every natural number is a product of atleast one factor pair. Eg- Factors of 51 are 1 , 3 , 17 , 51. So, factors of 51 in pair are (1,51), (3,17).

How can we define factors?

In mathematics a factor is a number which divides into another without leaving any remainder. Or we can say, any two numbers that multiply to give a product are both factors of that product. It can be both positive or negative.

Properties of Factors

  • Every number is a factor of zero (0), since 51 x 0 = 0.
  • 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, 3, 17, 51 are exact divisors of 51.
  • Factors of 51 are 1, 3, 17, 51. Each factor divides 51 without leaving a remainder.

Steps to find Factors of 51

  • Step 1. Find all the numbers that would divide 51 without leaving any remainder. Starting with the number 1 upto 25 (half of 51). The number 1 and the number itself are always factors of the given number.
    51 ÷ 1 : Remainder = 0
    51 ÷ 3 : Remainder = 0
    51 ÷ 17 : Remainder = 0
    51 ÷ 51 : Remainder = 0

Hence, Factors of 51 are 1, 3, 17, and 51
