Given numbers are 621, 728, 732, 213

The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 732 are 2 x 2 x 3 x 61

Prime factors of 213 are 3 x 71

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

Given numbers are 621, 728, 732, 213

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

Apply this formula for all numbers.

Step1:

LCM(621, 728) = 452088

GCD(621, 728) = ( 621 x 728 ) / 452088

= 621 / 728

= 621

Step2:

LCM(1, 732) = 732

GCD(1, 732) = ( 1 x 732 ) / 732

= 1 / 732

= 1

Step3:

LCM(1, 213) = 213

GCD(1, 213) = ( 1 x 213 ) / 213

= 1 / 213

= 1

So, Greatest Common Divisor of 621, 728, 732, 213 is 1
