Given numbers are 472, 774, 136, 640

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

Apply this formula for all numbers.

Step1:

LCM(472, 774) = 182664

GCD(472, 774) = ( 472 x 774 ) / 182664

= 472 / 774

= 472

Step2:

LCM(2, 136) = 136

GCD(2, 136) = ( 2 x 136 ) / 136

= 2 / 136

= 2

Step3:

LCM(2, 640) = 640

GCD(2, 640) = ( 2 x 640 ) / 640

= 2 / 640

= 2

So, Greatest Common Divisor of 472, 774, 136, 640 is 2
