Given numbers are 615, 817, 162, 440

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 817 are 19 x 43

Prime factors of 162 are 2 x 3 x 3 x 3 x 3

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

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

Given numbers are 615, 817, 162, 440

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

Apply this formula for all numbers.

Step1:

LCM(615, 817) = 502455

GCD(615, 817) = ( 615 x 817 ) / 502455

= 615 / 817

= 615

Step2:

LCM(1, 162) = 162

GCD(1, 162) = ( 1 x 162 ) / 162

= 1 / 162

= 1

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 615, 817, 162, 440 is 1
