Given numbers are 656, 686, 748, 359

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

Apply this formula for all numbers.

Step1:

LCM(656, 686) = 225008

GCD(656, 686) = ( 656 x 686 ) / 225008

= 656 / 686

= 656

Step2:

LCM(2, 748) = 748

GCD(2, 748) = ( 2 x 748 ) / 748

= 2 / 748

= 2

Step3:

LCM(2, 359) = 718

GCD(2, 359) = ( 2 x 359 ) / 718

= 2 / 359

= 2

So, Greatest Common Divisor of 656, 686, 748, 359 is 1
