Given numbers are 396, 212, 231, 642

The list of prime factors of all numbers are

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 212 are 2 x 2 x 53

Prime factors of 231 are 3 x 7 x 11

Prime factors of 642 are 2 x 3 x 107

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

Given numbers are 396, 212, 231, 642

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

Apply this formula for all numbers.

Step1:

LCM(396, 212) = 20988

GCD(396, 212) = ( 396 x 212 ) / 20988

= 396 / 212

= 396

Step2:

LCM(4, 231) = 924

GCD(4, 231) = ( 4 x 231 ) / 924

= 4 / 231

= 4

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 396, 212, 231, 642 is 1
