Given numbers are 204, 420, 63, 127

The list of prime factors of all numbers are

Prime factors of 204 are 2 x 2 x 3 x 17

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 63 are 3 x 3 x 7

Prime factors of 127 are 127

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

Given numbers are 204, 420, 63, 127

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

Apply this formula for all numbers.

Step1:

LCM(204, 420) = 7140

GCD(204, 420) = ( 204 x 420 ) / 7140

= 204 / 420

= 204

Step2:

LCM(12, 63) = 252

GCD(12, 63) = ( 12 x 63 ) / 252

= 12 / 63

= 12

Step3:

LCM(3, 127) = 381

GCD(3, 127) = ( 3 x 127 ) / 381

= 3 / 127

= 3

So, Greatest Common Divisor of 204, 420, 63, 127 is 1
