Given numbers are 105, 591, 287, 180

The list of prime factors of all numbers are

Prime factors of 105 are 3 x 5 x 7

Prime factors of 591 are 3 x 197

Prime factors of 287 are 7 x 41

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 105, 591, 287, 180

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

Apply this formula for all numbers.

Step1:

LCM(105, 591) = 20685

GCD(105, 591) = ( 105 x 591 ) / 20685

= 105 / 591

= 105

Step2:

LCM(3, 287) = 861

GCD(3, 287) = ( 3 x 287 ) / 861

= 3 / 287

= 3

Step3:

LCM(1, 180) = 180

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

= 1 / 180

= 1

So, Greatest Common Divisor of 105, 591, 287, 180 is 1
