Given numbers are 721, 305, 580, 610

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 305 are 5 x 61

Prime factors of 580 are 2 x 2 x 5 x 29

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 721, 305, 580, 610

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

Apply this formula for all numbers.

Step1:

LCM(721, 305) = 219905

GCD(721, 305) = ( 721 x 305 ) / 219905

= 721 / 305

= 721

Step2:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

Step3:

LCM(1, 610) = 610

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

= 1 / 610

= 1

So, Greatest Common Divisor of 721, 305, 580, 610 is 1
