Given numbers are 687, 660, 718, 853

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 718 are 2 x 359

Prime factors of 853 are 853

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

Given numbers are 687, 660, 718, 853

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

Apply this formula for all numbers.

Step1:

LCM(687, 660) = 151140

GCD(687, 660) = ( 687 x 660 ) / 151140

= 687 / 660

= 687

Step2:

LCM(3, 718) = 2154

GCD(3, 718) = ( 3 x 718 ) / 2154

= 3 / 718

= 3

Step3:

LCM(1, 853) = 853

GCD(1, 853) = ( 1 x 853 ) / 853

= 1 / 853

= 1

So, Greatest Common Divisor of 687, 660, 718, 853 is 1
