Given numbers are 656, 928, 974, 421

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

Apply this formula for all numbers.

Step1:

LCM(656, 928) = 38048

GCD(656, 928) = ( 656 x 928 ) / 38048

= 656 / 928

= 656

Step2:

LCM(16, 974) = 7792

GCD(16, 974) = ( 16 x 974 ) / 7792

= 16 / 974

= 16

Step3:

LCM(2, 421) = 842

GCD(2, 421) = ( 2 x 421 ) / 842

= 2 / 421

= 2

So, Greatest Common Divisor of 656, 928, 974, 421 is 1
