Given numbers are 639, 846, 645, 636

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

Apply this formula for all numbers.

Step1:

LCM(639, 846) = 60066

GCD(639, 846) = ( 639 x 846 ) / 60066

= 639 / 846

= 639

Step2:

LCM(9, 645) = 1935

GCD(9, 645) = ( 9 x 645 ) / 1935

= 9 / 645

= 9

Step3:

LCM(3, 636) = 636

GCD(3, 636) = ( 3 x 636 ) / 636

= 3 / 636

= 3

So, Greatest Common Divisor of 639, 846, 645, 636 is 3
