How to find factors of 12 that add upto 21

Steps to find factors of 12 that add upto 21

Example: Find factors of 12 that add upto 21

  • Sum of 1, 2, 6, and 12 : 1 + 2 + 6 + 12 = 21

Hence, factors of 12 that add upto 21 are 1, 2, 6, and 12.

Steps to find Factors of 12

  • Step 1. Find all the numbers that would divide 12 without leaving any remainder. Starting with the number 1 upto 6 (half of 12). The number 1 and the number itself are always factors of the given number.
    12 ÷ 1 : Remainder = 0
    12 ÷ 2 : Remainder = 0
    12 ÷ 3 : Remainder = 0
    12 ÷ 4 : Remainder = 0
    12 ÷ 6 : Remainder = 0
    12 ÷ 12 : Remainder = 0

Hence, Factors of 12 are 1, 2, 3, 4, 6, and 12

What are factors?

In mathematics, the term factor is used for that number which divides the other number to leave 0 as a remainder. A factor of a number can be positive or negative.

Properties of Factors

  • Factors and multiples are two different terms. Factors are those number which when multiplied together give the number itself, on the other hand multiples are what we get after multiplying the same number with and other number.
  • Prime factors are those factors which are further divisible by only two numbers i.e. 1 ans the factor itself.
  • Every number is a factor of zero (0), since 12 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, 3, 4, 6, 12 are exact divisors of 12.
