Given numbers are 815, 680, 474, 484

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 474 are 2 x 3 x 79

Prime factors of 484 are 2 x 2 x 11 x 11

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

Given numbers are 815, 680, 474, 484

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

Apply this formula for all numbers.

Step1:

LCM(815, 680) = 110840

GCD(815, 680) = ( 815 x 680 ) / 110840

= 815 / 680

= 815

Step2:

LCM(5, 474) = 2370

GCD(5, 474) = ( 5 x 474 ) / 2370

= 5 / 474

= 5

Step3:

LCM(1, 484) = 484

GCD(1, 484) = ( 1 x 484 ) / 484

= 1 / 484

= 1

So, Greatest Common Divisor of 815, 680, 474, 484 is 1
