The list of prime factors of all numbers are

Prime factors of 415 are 5 x 83

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

Prime factors of 715 are 5 x 11 x 13

Prime factors of 247 are 13 x 19

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

Given numbers are 415, 664, 715, 247

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

Apply this formula for all numbers.

Step1:

LCM(415, 664) = 3320

GCD(415, 664) = ( 415 x 664 ) / 3320

= 415 / 664

= 415

Step2:

LCM(83, 715) = 59345

GCD(83, 715) = ( 83 x 715 ) / 59345

= 83 / 715

= 83

Step3:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

So, Greatest Common Divisor of 415, 664, 715, 247 is 1
