Given numbers are 981, 352, 455, 615

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 352 are 2 x 2 x 2 x 2 x 2 x 11

Prime factors of 455 are 5 x 7 x 13

Prime factors of 615 are 3 x 5 x 41

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

Given numbers are 981, 352, 455, 615

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

Apply this formula for all numbers.

Step1:

LCM(981, 352) = 345312

GCD(981, 352) = ( 981 x 352 ) / 345312

= 981 / 352

= 981

Step2:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

Step3:

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

= 1 / 615

= 1

So, Greatest Common Divisor of 981, 352, 455, 615 is 1
