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

Apply this formula for all numbers.

Step1:

LCM(656, 436) = 71504

GCD(656, 436) = ( 656 x 436 ) / 71504

= 656 / 436

= 656

Step2:

LCM(4, 990) = 1980

GCD(4, 990) = ( 4 x 990 ) / 1980

= 4 / 990

= 4

Step3:

LCM(2, 732) = 732

GCD(2, 732) = ( 2 x 732 ) / 732

= 2 / 732

= 2

So, Greatest Common Divisor of 656, 436, 990, 732 is 2
