Given numbers are 213, 631, 620, 638

The list of prime factors of all numbers are

Prime factors of 213 are 3 x 71

Prime factors of 631 are 631

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

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 213, 631, 620, 638

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

Apply this formula for all numbers.

Step1:

LCM(213, 631) = 134403

GCD(213, 631) = ( 213 x 631 ) / 134403

= 213 / 631

= 213

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 213, 631, 620, 638 is 1
