Given numbers are 615, 457, 420, 882

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 457 are 457

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 882 are 2 x 3 x 3 x 7 x 7

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

Given numbers are 615, 457, 420, 882

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

Apply this formula for all numbers.

Step1:

LCM(615, 457) = 281055

GCD(615, 457) = ( 615 x 457 ) / 281055

= 615 / 457

= 615

Step2:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

Step3:

LCM(1, 882) = 882

GCD(1, 882) = ( 1 x 882 ) / 882

= 1 / 882

= 1

So, Greatest Common Divisor of 615, 457, 420, 882 is 1
