Steps to find factors of 513 in pair

Example: Find factors of 513 in pair

Factor Pair Pair Factorization
1 and 513 1 x 513 = 513
3 and 171 3 x 171 = 513
9 and 57 9 x 57 = 513
19 and 27 19 x 27 = 513

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 513. They are called negative pair factors.

Hence, the negative pairs of 513 would be ( -1 , -513 ) .

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 513 are 1 , 3 , 9 , 19 , 27 , 57 , 171 , 513. So, factors of 513 in pair are (1,513), (3,171), (9,57), (19,27).

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

  • Every factor of a number is an exact divisor of that number, example 1, 3, 9, 19, 27, 57, 171, 513 are exact divisors of 513.
  • Every number other than 1 has at least two factors, namely the number itself and 1.
  • Each number is a factor of itself. Eg. 513 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 513.

Steps to find Factors of 513

  • Step 1. Find all the numbers that would divide 513 without leaving any remainder. Starting with the number 1 upto 256 (half of 513). The number 1 and the number itself are always factors of the given number.
    513 ÷ 1 : Remainder = 0
    513 ÷ 3 : Remainder = 0
    513 ÷ 9 : Remainder = 0
    513 ÷ 19 : Remainder = 0
    513 ÷ 27 : Remainder = 0
    513 ÷ 57 : Remainder = 0
    513 ÷ 171 : Remainder = 0
    513 ÷ 513 : Remainder = 0

Hence, Factors of 513 are 1, 3, 9, 19, 27, 57, 171, and 513
