Given numbers are 297, 228, 20, 168

The list of prime factors of all numbers are

Prime factors of 297 are 3 x 3 x 3 x 11

Prime factors of 228 are 2 x 2 x 3 x 19

Prime factors of 20 are 2 x 2 x 5

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

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

Given numbers are 297, 228, 20, 168

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

Apply this formula for all numbers.

Step1:

LCM(297, 228) = 22572

GCD(297, 228) = ( 297 x 228 ) / 22572

= 297 / 228

= 297

Step2:

LCM(3, 20) = 60

GCD(3, 20) = ( 3 x 20 ) / 60

= 3 / 20

= 3

Step3:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

So, Greatest Common Divisor of 297, 228, 20, 168 is 1
