Given numbers are 249, 361, 858, 360

The list of prime factors of all numbers are

Prime factors of 249 are 3 x 83

Prime factors of 361 are 19 x 19

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 360 are 2 x 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 249, 361, 858, 360

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

Apply this formula for all numbers.

Step1:

LCM(249, 361) = 89889

GCD(249, 361) = ( 249 x 361 ) / 89889

= 249 / 361

= 249

Step2:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

Step3:

LCM(1, 360) = 360

GCD(1, 360) = ( 1 x 360 ) / 360

= 1 / 360

= 1

So, Greatest Common Divisor of 249, 361, 858, 360 is 1
