Given numbers are 855, 656, 145, 631

The list of prime factors of all numbers are

Prime factors of 855 are 3 x 3 x 5 x 19

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

Prime factors of 145 are 5 x 29

Prime factors of 631 are 631

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

Given numbers are 855, 656, 145, 631

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

Apply this formula for all numbers.

Step1:

LCM(855, 656) = 560880

GCD(855, 656) = ( 855 x 656 ) / 560880

= 855 / 656

= 855

Step2:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

Step3:

LCM(1, 631) = 631

GCD(1, 631) = ( 1 x 631 ) / 631

= 1 / 631

= 1

So, Greatest Common Divisor of 855, 656, 145, 631 is 1
