Given numbers are 651, 392, 208, 640

The list of prime factors of all numbers are

Prime factors of 651 are 3 x 7 x 31

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 651, 392, 208, 640

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

Apply this formula for all numbers.

Step1:

LCM(651, 392) = 36456

GCD(651, 392) = ( 651 x 392 ) / 36456

= 651 / 392

= 651

Step2:

LCM(7, 208) = 1456

GCD(7, 208) = ( 7 x 208 ) / 1456

= 7 / 208

= 7

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 651, 392, 208, 640 is 1
