Given numbers are 680, 181, 817, 915

The list of prime factors of all numbers are

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

Prime factors of 181 are 181

Prime factors of 817 are 19 x 43

Prime factors of 915 are 3 x 5 x 61

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

Given numbers are 680, 181, 817, 915

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

Apply this formula for all numbers.

Step1:

LCM(680, 181) = 123080

GCD(680, 181) = ( 680 x 181 ) / 123080

= 680 / 181

= 680

Step2:

LCM(1, 817) = 817

GCD(1, 817) = ( 1 x 817 ) / 817

= 1 / 817

= 1

Step3:

LCM(1, 915) = 915

GCD(1, 915) = ( 1 x 915 ) / 915

= 1 / 915

= 1

So, Greatest Common Divisor of 680, 181, 817, 915 is 1
