Given numbers are 915, 392, 820, 452

The list of prime factors of all numbers are

Prime factors of 915 are 3 x 5 x 61

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 452 are 2 x 2 x 113

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

Given numbers are 915, 392, 820, 452

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

Apply this formula for all numbers.

Step1:

LCM(915, 392) = 358680

GCD(915, 392) = ( 915 x 392 ) / 358680

= 915 / 392

= 915

Step2:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

Step3:

LCM(1, 452) = 452

GCD(1, 452) = ( 1 x 452 ) / 452

= 1 / 452

= 1

So, Greatest Common Divisor of 915, 392, 820, 452 is 1
