Given numbers are 851, 866, 638, 656

The list of prime factors of all numbers are

Prime factors of 851 are 23 x 37

Prime factors of 866 are 2 x 433

Prime factors of 638 are 2 x 11 x 29

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

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

Given numbers are 851, 866, 638, 656

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

Apply this formula for all numbers.

Step1:

LCM(851, 866) = 736966

GCD(851, 866) = ( 851 x 866 ) / 736966

= 851 / 866

= 851

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

Step3:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

So, Greatest Common Divisor of 851, 866, 638, 656 is 1
