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

Apply this formula for all numbers.

Step1:

LCM(636, 189) = 40068

GCD(636, 189) = ( 636 x 189 ) / 40068

= 636 / 189

= 636

Step2:

LCM(3, 255) = 255

GCD(3, 255) = ( 3 x 255 ) / 255

= 3 / 255

= 3

Step3:

LCM(3, 957) = 957

GCD(3, 957) = ( 3 x 957 ) / 957

= 3 / 957

= 3

So, Greatest Common Divisor of 636, 189, 255, 957 is 3
