Given numbers are 656, 140, 470, 797

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

Apply this formula for all numbers.

Step1:

LCM(656, 140) = 22960

GCD(656, 140) = ( 656 x 140 ) / 22960

= 656 / 140

= 656

Step2:

LCM(4, 470) = 940

GCD(4, 470) = ( 4 x 470 ) / 940

= 4 / 470

= 4

Step3:

LCM(2, 797) = 1594

GCD(2, 797) = ( 2 x 797 ) / 1594

= 2 / 797

= 2

So, Greatest Common Divisor of 656, 140, 470, 797 is 1
