The list of prime factors of all numbers are

Prime factors of 398 are 2 x 199

Prime factors of 608 are 2 x 2 x 2 x 2 x 2 x 19

Prime factors of 915 are 3 x 5 x 61

Prime factors of 147 are 3 x 7 x 7

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

Given numbers are 398, 608, 915, 147

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

Apply this formula for all numbers.

Step1:

LCM(398, 608) = 120992

GCD(398, 608) = ( 398 x 608 ) / 120992

= 398 / 608

= 398

Step2:

LCM(2, 915) = 1830

GCD(2, 915) = ( 2 x 915 ) / 1830

= 2 / 915

= 2

Step3:

LCM(1, 147) = 147

GCD(1, 147) = ( 1 x 147 ) / 147

= 1 / 147

= 1

So, Greatest Common Divisor of 398, 608, 915, 147 is 1
