Given numbers are 363, 135, 457, 420

The list of prime factors of all numbers are

Prime factors of 363 are 3 x 11 x 11

Prime factors of 135 are 3 x 3 x 3 x 5

Prime factors of 457 are 457

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

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

Given numbers are 363, 135, 457, 420

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

Apply this formula for all numbers.

Step1:

LCM(363, 135) = 16335

GCD(363, 135) = ( 363 x 135 ) / 16335

= 363 / 135

= 363

Step2:

LCM(3, 457) = 1371

GCD(3, 457) = ( 3 x 457 ) / 1371

= 3 / 457

= 3

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 363, 135, 457, 420 is 1
