Given numbers are 213, 510, 315, 721

The list of prime factors of all numbers are

Prime factors of 213 are 3 x 71

Prime factors of 510 are 2 x 3 x 5 x 17

Prime factors of 315 are 3 x 3 x 5 x 7

Prime factors of 721 are 7 x 103

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

Given numbers are 213, 510, 315, 721

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

Apply this formula for all numbers.

Step1:

LCM(213, 510) = 36210

GCD(213, 510) = ( 213 x 510 ) / 36210

= 213 / 510

= 213

Step2:

LCM(3, 315) = 315

GCD(3, 315) = ( 3 x 315 ) / 315

= 3 / 315

= 3

Step3:

LCM(3, 721) = 2163

GCD(3, 721) = ( 3 x 721 ) / 2163

= 3 / 721

= 3

So, Greatest Common Divisor of 213, 510, 315, 721 is 1
