Given numbers are 660, 452, 780, 656

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

Apply this formula for all numbers.

Step1:

LCM(660, 452) = 74580

GCD(660, 452) = ( 660 x 452 ) / 74580

= 660 / 452

= 660

Step2:

LCM(4, 780) = 780

GCD(4, 780) = ( 4 x 780 ) / 780

= 4 / 780

= 4

Step3:

LCM(4, 656) = 656

GCD(4, 656) = ( 4 x 656 ) / 656

= 4 / 656

= 4

So, Greatest Common Divisor of 660, 452, 780, 656 is 4
