Given numbers are 640, 253, 64

The list of prime factors of all numbers are

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

Prime factors of 253 are 11 x 23

Prime factors of 64 are 2 x 2 x 2 x 2 x 2 x 2

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

Given numbers are 640, 253, 64

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

Apply this formula for all numbers.

Step1:

LCM(640, 253) = 161920

GCD(640, 253) = ( 640 x 253 ) / 161920

= 640 / 253

= 640

Step2:

LCM(1, 64) = 64

GCD(1, 64) = ( 1 x 64 ) / 64

= 1 / 64

= 1

So, Greatest Common Divisor of 640, 253, 64 is 1
