Given numbers are 520, 785, 721, 238

The list of prime factors of all numbers are

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 785 are 5 x 157

Prime factors of 721 are 7 x 103

Prime factors of 238 are 2 x 7 x 17

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

Given numbers are 520, 785, 721, 238

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

Apply this formula for all numbers.

Step1:

LCM(520, 785) = 81640

GCD(520, 785) = ( 520 x 785 ) / 81640

= 520 / 785

= 520

Step2:

LCM(5, 721) = 3605

GCD(5, 721) = ( 5 x 721 ) / 3605

= 5 / 721

= 5

Step3:

LCM(1, 238) = 238

GCD(1, 238) = ( 1 x 238 ) / 238

= 1 / 238

= 1

So, Greatest Common Divisor of 520, 785, 721, 238 is 1
