Given numbers are 143, 204, 420, 555

The list of prime factors of all numbers are

Prime factors of 143 are 11 x 13

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 555 are 3 x 5 x 37

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

Given numbers are 143, 204, 420, 555

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

Apply this formula for all numbers.

Step1:

LCM(143, 204) = 29172

GCD(143, 204) = ( 143 x 204 ) / 29172

= 143 / 204

= 143

Step2:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

Step3:

LCM(1, 555) = 555

GCD(1, 555) = ( 1 x 555 ) / 555

= 1 / 555

= 1

So, Greatest Common Divisor of 143, 204, 420, 555 is 1
