Given numbers are 615, 704, 981, 945

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 704 are 2 x 2 x 2 x 2 x 2 x 2 x 11

Prime factors of 981 are 3 x 3 x 109

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

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

Given numbers are 615, 704, 981, 945

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

Apply this formula for all numbers.

Step1:

LCM(615, 704) = 432960

GCD(615, 704) = ( 615 x 704 ) / 432960

= 615 / 704

= 615

Step2:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

Step3:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

So, Greatest Common Divisor of 615, 704, 981, 945 is 1
