Given numbers are 480, 906, 391, 249

The list of prime factors of all numbers are

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 906 are 2 x 3 x 151

Prime factors of 391 are 17 x 23

Prime factors of 249 are 3 x 83

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

Given numbers are 480, 906, 391, 249

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

Apply this formula for all numbers.

Step1:

LCM(480, 906) = 72480

GCD(480, 906) = ( 480 x 906 ) / 72480

= 480 / 906

= 480

Step2:

LCM(6, 391) = 2346

GCD(6, 391) = ( 6 x 391 ) / 2346

= 6 / 391

= 6

Step3:

LCM(1, 249) = 249

GCD(1, 249) = ( 1 x 249 ) / 249

= 1 / 249

= 1

So, Greatest Common Divisor of 480, 906, 391, 249 is 1
