Given numbers are 715, 398, 147, 404

The list of prime factors of all numbers are

Prime factors of 715 are 5 x 11 x 13

Prime factors of 398 are 2 x 199

Prime factors of 147 are 3 x 7 x 7

Prime factors of 404 are 2 x 2 x 101

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

Given numbers are 715, 398, 147, 404

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

Apply this formula for all numbers.

Step1:

LCM(715, 398) = 284570

GCD(715, 398) = ( 715 x 398 ) / 284570

= 715 / 398

= 715

Step2:

LCM(1, 147) = 147

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

= 1 / 147

= 1

Step3:

LCM(1, 404) = 404

GCD(1, 404) = ( 1 x 404 ) / 404

= 1 / 404

= 1

So, Greatest Common Divisor of 715, 398, 147, 404 is 1
