Given numbers are 816, 580, 660, 636

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

Apply this formula for all numbers.

Step1:

LCM(816, 580) = 118320

GCD(816, 580) = ( 816 x 580 ) / 118320

= 816 / 580

= 816

Step2:

LCM(4, 660) = 660

GCD(4, 660) = ( 4 x 660 ) / 660

= 4 / 660

= 4

Step3:

LCM(4, 636) = 636

GCD(4, 636) = ( 4 x 636 ) / 636

= 4 / 636

= 4

So, Greatest Common Divisor of 816, 580, 660, 636 is 4
