Given numbers are 640, 936, 66, 204

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

Apply this formula for all numbers.

Step1:

LCM(640, 936) = 74880

GCD(640, 936) = ( 640 x 936 ) / 74880

= 640 / 936

= 640

Step2:

LCM(8, 66) = 264

GCD(8, 66) = ( 8 x 66 ) / 264

= 8 / 66

= 8

Step3:

LCM(2, 204) = 204

GCD(2, 204) = ( 2 x 204 ) / 204

= 2 / 204

= 2

So, Greatest Common Divisor of 640, 936, 66, 204 is 2
