Given numbers are 664, 390, 651, 619

The list of prime factors of all numbers are

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

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 651 are 3 x 7 x 31

Prime factors of 619 are 619

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

Given numbers are 664, 390, 651, 619

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

Apply this formula for all numbers.

Step1:

LCM(664, 390) = 129480

GCD(664, 390) = ( 664 x 390 ) / 129480

= 664 / 390

= 664

Step2:

LCM(2, 651) = 1302

GCD(2, 651) = ( 2 x 651 ) / 1302

= 2 / 651

= 2

Step3:

LCM(1, 619) = 619

GCD(1, 619) = ( 1 x 619 ) / 619

= 1 / 619

= 1

So, Greatest Common Divisor of 664, 390, 651, 619 is 1
