Given numbers are 385, 203, 459, 180

The list of prime factors of all numbers are

Prime factors of 385 are 5 x 7 x 11

Prime factors of 203 are 7 x 29

Prime factors of 459 are 3 x 3 x 3 x 17

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

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

Given numbers are 385, 203, 459, 180

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

Apply this formula for all numbers.

Step1:

LCM(385, 203) = 11165

GCD(385, 203) = ( 385 x 203 ) / 11165

= 385 / 203

= 385

Step2:

LCM(7, 459) = 3213

GCD(7, 459) = ( 7 x 459 ) / 3213

= 7 / 459

= 7

Step3:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

So, Greatest Common Divisor of 385, 203, 459, 180 is 1
