Steps to find Factors of 840

Step 1. Find all the numbers that would divide 840 without leaving any remainder. Starting with the number 1 upto 420 (half of 840). The number 1 and the number itself are always factors of the given number.

840 ÷ 1 : Remainder = 0

840 ÷ 2 : Remainder = 0

840 ÷ 3 : Remainder = 0

840 ÷ 4 : Remainder = 0

840 ÷ 5 : Remainder = 0

840 ÷ 6 : Remainder = 0

840 ÷ 7 : Remainder = 0

840 ÷ 8 : Remainder = 0

840 ÷ 10 : Remainder = 0

840 ÷ 12 : Remainder = 0

840 ÷ 14 : Remainder = 0

840 ÷ 15 : Remainder = 0

840 ÷ 20 : Remainder = 0

840 ÷ 21 : Remainder = 0

840 ÷ 24 : Remainder = 0

840 ÷ 28 : Remainder = 0

840 ÷ 30 : Remainder = 0

840 ÷ 35 : Remainder = 0

840 ÷ 40 : Remainder = 0

840 ÷ 42 : Remainder = 0

840 ÷ 56 : Remainder = 0

840 ÷ 60 : Remainder = 0

840 ÷ 70 : Remainder = 0

840 ÷ 84 : Remainder = 0

840 ÷ 105 : Remainder = 0

840 ÷ 120 : Remainder = 0

840 ÷ 140 : Remainder = 0

840 ÷ 168 : Remainder = 0

840 ÷ 210 : Remainder = 0

840 ÷ 280 : Remainder = 0

840 ÷ 420 : Remainder = 0

840 ÷ 840 : Remainder = 0

Hence, Factors of 840 are 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, and 840

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 840 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, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840 are exact divisors of 840.
