Given numbers are 820, 957, 684, 715

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 957 are 3 x 11 x 29

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 715 are 5 x 11 x 13

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

Given numbers are 820, 957, 684, 715

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(820, 957) = 784740

GCD(820, 957) = ( 820 x 957 ) / 784740

= 820 / 957

= 820

Step2:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

Step3:

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

= 1 / 715

= 1

So, Greatest Common Divisor of 820, 957, 684, 715 is 1
