Example: Find factors of 2420 in pair

Factor Pair Pair Factorization
1 and 2420 1 x 2420 = 2420
2 and 1210 2 x 1210 = 2420
4 and 605 4 x 605 = 2420
5 and 484 5 x 484 = 2420
10 and 242 10 x 242 = 2420
11 and 220 11 x 220 = 2420
20 and 121 20 x 121 = 2420
22 and 110 22 x 110 = 2420
44 and 55 44 x 55 = 2420

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 2420. They are called negative pair factors.

Hence, the negative pairs of 2420 would be ( -1 , -2420 ) .

Definition of factor pairs?

In mathematics, factor pair are often given as pair of numbers which when multiplied together give the original number. Every natural number is a product of atleast one factor pair. Eg- Factors of 2420 are 1 , 2 , 4 , 5 , 10 , 11 , 20 , 22 , 44 , 55 , 110 , 121 , 220 , 242 , 484 , 605 , 1210 , 2420. So, factors of 2420 in pair are (1,2420), (2,1210), (4,605), (5,484), (10,242), (11,220), (20,121), (22,110), (44,55).

What are factors?

In mathematics, a factor is that number which divides into another number exactly, without leaving a remainder. A factor of a number can be positive or negative.

Properties of Factors

  • Each number is a factor of itself. Eg. 2420 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 2420.
  • Every number is a factor of zero (0), since 2420 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, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 121, 220, 242, 484, 605, 1210, 2420 are exact divisors of 2420.
  • Factors of 2420 are 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 121, 220, 242, 484, 605, 1210, 2420. Each factor divides 2420 without leaving a remainder.
  • Every factor of a number is less than or equal to the number, eg. 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 121, 220, 242, 484, 605, 1210, 2420 are all less than or equal to 2420.

Steps to find Factors of 2420

  • Step 1. Find all the numbers that would divide 2420 without leaving any remainder. Starting with the number 1 upto 1210 (half of 2420). The number 1 and the number itself are always factors of the given number.
    2420 ÷ 1 : Remainder = 0
    2420 ÷ 2 : Remainder = 0
    2420 ÷ 4 : Remainder = 0
    2420 ÷ 5 : Remainder = 0
    2420 ÷ 10 : Remainder = 0
    2420 ÷ 11 : Remainder = 0
    2420 ÷ 20 : Remainder = 0
    2420 ÷ 22 : Remainder = 0
    2420 ÷ 44 : Remainder = 0
    2420 ÷ 55 : Remainder = 0
    2420 ÷ 110 : Remainder = 0
    2420 ÷ 121 : Remainder = 0
    2420 ÷ 220 : Remainder = 0
    2420 ÷ 242 : Remainder = 0
    2420 ÷ 484 : Remainder = 0
    2420 ÷ 605 : Remainder = 0
    2420 ÷ 1210 : Remainder = 0
    2420 ÷ 2420 : Remainder = 0

Hence, Factors of 2420 are 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 121, 220, 242, 484, 605, 1210, and 2420
