Given numbers are 214, 456, 90, 639

The list of prime factors of all numbers are

Prime factors of 214 are 2 x 107

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 90 are 2 x 3 x 3 x 5

Prime factors of 639 are 3 x 3 x 71

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

Given numbers are 214, 456, 90, 639

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

Apply this formula for all numbers.

Step1:

LCM(214, 456) = 48792

GCD(214, 456) = ( 214 x 456 ) / 48792

= 214 / 456

= 214

Step2:

LCM(2, 90) = 90

GCD(2, 90) = ( 2 x 90 ) / 90

= 2 / 90

= 2

Step3:

LCM(2, 639) = 1278

GCD(2, 639) = ( 2 x 639 ) / 1278

= 2 / 639

= 2

So, Greatest Common Divisor of 214, 456, 90, 639 is 1
