Given numbers are 428, 880, 720, 315

The list of prime factors of all numbers are

Prime factors of 428 are 2 x 2 x 107

Prime factors of 880 are 2 x 2 x 2 x 2 x 5 x 11

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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

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

Given numbers are 428, 880, 720, 315

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

Apply this formula for all numbers.

Step1:

LCM(428, 880) = 94160

GCD(428, 880) = ( 428 x 880 ) / 94160

= 428 / 880

= 428

Step2:

LCM(4, 720) = 720

GCD(4, 720) = ( 4 x 720 ) / 720

= 4 / 720

= 4

Step3:

LCM(4, 315) = 1260

GCD(4, 315) = ( 4 x 315 ) / 1260

= 4 / 315

= 4

So, Greatest Common Divisor of 428, 880, 720, 315 is 1
