Given numbers are 664, 394, 456, 517

The list of prime factors of all numbers are

Prime factors of 664 are 2 x 2 x 2 x 83

Prime factors of 394 are 2 x 197

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 517 are 11 x 47

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

Given numbers are 664, 394, 456, 517

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

Apply this formula for all numbers.

Step1:

LCM(664, 394) = 130808

GCD(664, 394) = ( 664 x 394 ) / 130808

= 664 / 394

= 664

Step2:

LCM(2, 456) = 456

GCD(2, 456) = ( 2 x 456 ) / 456

= 2 / 456

= 2

Step3:

LCM(2, 517) = 1034

GCD(2, 517) = ( 2 x 517 ) / 1034

= 2 / 517

= 2

So, Greatest Common Divisor of 664, 394, 456, 517 is 1
