Given numbers are 640, 544, 672, 279

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 544 are 2 x 2 x 2 x 2 x 2 x 17

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 279 are 3 x 3 x 31

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

Given numbers are 640, 544, 672, 279

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

Apply this formula for all numbers.

Step1:

LCM(640, 544) = 10880

GCD(640, 544) = ( 640 x 544 ) / 10880

= 640 / 544

= 640

Step2:

LCM(32, 672) = 672

GCD(32, 672) = ( 32 x 672 ) / 672

= 32 / 672

= 32

Step3:

LCM(32, 279) = 8928

GCD(32, 279) = ( 32 x 279 ) / 8928

= 32 / 279

= 32

So, Greatest Common Divisor of 640, 544, 672, 279 is 1
