Given numbers are 517, 620, 721, 244

The list of prime factors of all numbers are

Prime factors of 517 are 11 x 47

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 721 are 7 x 103

Prime factors of 244 are 2 x 2 x 61

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

Given numbers are 517, 620, 721, 244

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

Apply this formula for all numbers.

Step1:

LCM(517, 620) = 320540

GCD(517, 620) = ( 517 x 620 ) / 320540

= 517 / 620

= 517

Step2:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

Step3:

LCM(1, 244) = 244

GCD(1, 244) = ( 1 x 244 ) / 244

= 1 / 244

= 1

So, Greatest Common Divisor of 517, 620, 721, 244 is 1
