Given Input Data is 870, 520, 977, 280

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 870 is 2 x 3 x 5 x 29

Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13

Prime Factorization of 977 is 977

Prime Factorization of 280 is 2 x 2 x 2 x 5 x 7

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(870, 520) = 45240

GCD(870, 520) = ( 870 x 520 ) / 45240

GCD(870, 520) = 452400 / 45240

GCD(870, 520) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 977

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(10, 977) = 9770

GCD(10, 977) = ( 10 x 977 ) / 9770

GCD(10, 977) = 9770 / 9770

GCD(10, 977) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 280

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

GCD(1, 280) = 280 / 280

GCD(1, 280) = 1

GCD of 870, 520, 977, 280 is 1
