Given numbers are 222, 168, 302, 645

The list of prime factors of all numbers are

Prime factors of 222 are 2 x 3 x 37

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 302 are 2 x 151

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 222, 168, 302, 645

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

Apply this formula for all numbers.

Step1:

LCM(222, 168) = 6216

GCD(222, 168) = ( 222 x 168 ) / 6216

= 222 / 168

= 222

Step2:

LCM(6, 302) = 906

GCD(6, 302) = ( 6 x 302 ) / 906

= 6 / 302

= 6

Step3:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

So, Greatest Common Divisor of 222, 168, 302, 645 is 1
