Given numbers are 656, 122, 371, 287

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

Apply this formula for all numbers.

Step1:

LCM(656, 122) = 40016

GCD(656, 122) = ( 656 x 122 ) / 40016

= 656 / 122

= 656

Step2:

LCM(2, 371) = 742

GCD(2, 371) = ( 2 x 371 ) / 742

= 2 / 371

= 2

Step3:

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

= 1 / 287

= 1

So, Greatest Common Divisor of 656, 122, 371, 287 is 1
