Given numbers are 640, 676, 216, 976

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

Apply this formula for all numbers.

Step1:

LCM(640, 676) = 108160

GCD(640, 676) = ( 640 x 676 ) / 108160

= 640 / 676

= 640

Step2:

LCM(4, 216) = 216

GCD(4, 216) = ( 4 x 216 ) / 216

= 4 / 216

= 4

Step3:

LCM(4, 976) = 976

GCD(4, 976) = ( 4 x 976 ) / 976

= 4 / 976

= 4

So, Greatest Common Divisor of 640, 676, 216, 976 is 4
