Given numbers are 640, 224, 517, 671

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 224 are 2 x 2 x 2 x 2 x 2 x 7

Prime factors of 517 are 11 x 47

Prime factors of 671 are 11 x 61

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

Given numbers are 640, 224, 517, 671

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

Apply this formula for all numbers.

Step1:

LCM(640, 224) = 4480

GCD(640, 224) = ( 640 x 224 ) / 4480

= 640 / 224

= 640

Step2:

LCM(32, 517) = 16544

GCD(32, 517) = ( 32 x 517 ) / 16544

= 32 / 517

= 32

Step3:

LCM(1, 671) = 671

GCD(1, 671) = ( 1 x 671 ) / 671

= 1 / 671

= 1

So, Greatest Common Divisor of 640, 224, 517, 671 is 1
