Given numbers are 656, 926, 997, 991

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

Apply this formula for all numbers.

Step1:

LCM(656, 926) = 303728

GCD(656, 926) = ( 656 x 926 ) / 303728

= 656 / 926

= 656

Step2:

LCM(2, 997) = 1994

GCD(2, 997) = ( 2 x 997 ) / 1994

= 2 / 997

= 2

Step3:

LCM(1, 991) = 991

GCD(1, 991) = ( 1 x 991 ) / 991

= 1 / 991

= 1

So, Greatest Common Divisor of 656, 926, 997, 991 is 1
