Given numbers are 640, 296, 221, 208

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

Apply this formula for all numbers.

Step1:

LCM(640, 296) = 23680

GCD(640, 296) = ( 640 x 296 ) / 23680

= 640 / 296

= 640

Step2:

LCM(8, 221) = 1768

GCD(8, 221) = ( 8 x 221 ) / 1768

= 8 / 221

= 8

Step3:

LCM(1, 208) = 208

GCD(1, 208) = ( 1 x 208 ) / 208

= 1 / 208

= 1

So, Greatest Common Divisor of 640, 296, 221, 208 is 1
