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

Given numbers are 656, 790, 390, 877

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

Apply this formula for all numbers.

Step1:

LCM(656, 790) = 259120

GCD(656, 790) = ( 656 x 790 ) / 259120

= 656 / 790

= 656

Step2:

LCM(2, 390) = 390

GCD(2, 390) = ( 2 x 390 ) / 390

= 2 / 390

= 2

Step3:

LCM(2, 877) = 1754

GCD(2, 877) = ( 2 x 877 ) / 1754

= 2 / 877

= 2

So, Greatest Common Divisor of 656, 790, 390, 877 is 1
