Given numbers are 407, 306, 122, 390

The list of prime factors of all numbers are

Prime factors of 407 are 11 x 37

Prime factors of 306 are 2 x 3 x 3 x 17

Prime factors of 122 are 2 x 61

Prime factors of 390 are 2 x 3 x 5 x 13

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

Given numbers are 407, 306, 122, 390

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

Apply this formula for all numbers.

Step1:

LCM(407, 306) = 124542

GCD(407, 306) = ( 407 x 306 ) / 124542

= 407 / 306

= 407

Step2:

LCM(1, 122) = 122

GCD(1, 122) = ( 1 x 122 ) / 122

= 1 / 122

= 1

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 407, 306, 122, 390 is 1
