Given numbers are 915, 784, 404, 393

The list of prime factors of all numbers are

Prime factors of 915 are 3 x 5 x 61

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

Prime factors of 404 are 2 x 2 x 101

Prime factors of 393 are 3 x 131

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

Given numbers are 915, 784, 404, 393

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

Apply this formula for all numbers.

Step1:

LCM(915, 784) = 717360

GCD(915, 784) = ( 915 x 784 ) / 717360

= 915 / 784

= 915

Step2:

LCM(1, 404) = 404

GCD(1, 404) = ( 1 x 404 ) / 404

= 1 / 404

= 1

Step3:

LCM(1, 393) = 393

GCD(1, 393) = ( 1 x 393 ) / 393

= 1 / 393

= 1

So, Greatest Common Divisor of 915, 784, 404, 393 is 1
