Given numbers are 717, 721, 990, 610

The list of prime factors of all numbers are

Prime factors of 717 are 3 x 239

Prime factors of 721 are 7 x 103

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

Prime factors of 610 are 2 x 5 x 61

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

Given numbers are 717, 721, 990, 610

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

Apply this formula for all numbers.

Step1:

LCM(717, 721) = 516957

GCD(717, 721) = ( 717 x 721 ) / 516957

= 717 / 721

= 717

Step2:

LCM(1, 990) = 990

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

= 1 / 990

= 1

Step3:

LCM(1, 610) = 610

GCD(1, 610) = ( 1 x 610 ) / 610

= 1 / 610

= 1

So, Greatest Common Divisor of 717, 721, 990, 610 is 1
