Given numbers are 918, 664, 315, 620

The list of prime factors of all numbers are

Prime factors of 918 are 2 x 3 x 3 x 3 x 17

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

Prime factors of 315 are 3 x 3 x 5 x 7

Prime factors of 620 are 2 x 2 x 5 x 31

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

Given numbers are 918, 664, 315, 620

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

Apply this formula for all numbers.

Step1:

LCM(918, 664) = 304776

GCD(918, 664) = ( 918 x 664 ) / 304776

= 918 / 664

= 918

Step2:

LCM(2, 315) = 630

GCD(2, 315) = ( 2 x 315 ) / 630

= 2 / 315

= 2

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 918, 664, 315, 620 is 1
