Given numbers are 615, 651, 82, 480

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 651 are 3 x 7 x 31

Prime factors of 82 are 2 x 41

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 615, 651, 82, 480

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

Apply this formula for all numbers.

Step1:

LCM(615, 651) = 133455

GCD(615, 651) = ( 615 x 651 ) / 133455

= 615 / 651

= 615

Step2:

LCM(3, 82) = 246

GCD(3, 82) = ( 3 x 82 ) / 246

= 3 / 82

= 3

Step3:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

So, Greatest Common Divisor of 615, 651, 82, 480 is 1
