Given numbers are 431, 791, 612, 390

The list of prime factors of all numbers are

Prime factors of 431 are 431

Prime factors of 791 are 7 x 113

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

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 431, 791, 612, 390

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

Apply this formula for all numbers.

Step1:

LCM(431, 791) = 340921

GCD(431, 791) = ( 431 x 791 ) / 340921

= 431 / 791

= 431

Step2:

LCM(1, 612) = 612

GCD(1, 612) = ( 1 x 612 ) / 612

= 1 / 612

= 1

Step3:

LCM(1, 390) = 390

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

= 1 / 390

= 1

So, Greatest Common Divisor of 431, 791, 612, 390 is 1
