Given numbers are 615, 666, 703, 990

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 666 are 2 x 3 x 3 x 37

Prime factors of 703 are 19 x 37

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

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

Given numbers are 615, 666, 703, 990

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

Apply this formula for all numbers.

Step1:

LCM(615, 666) = 136530

GCD(615, 666) = ( 615 x 666 ) / 136530

= 615 / 666

= 615

Step2:

LCM(3, 703) = 2109

GCD(3, 703) = ( 3 x 703 ) / 2109

= 3 / 703

= 3

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 615, 666, 703, 990 is 1
