Given numbers are 390, 326, 771, 667

The list of prime factors of all numbers are

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

Prime factors of 326 are 2 x 163

Prime factors of 771 are 3 x 257

Prime factors of 667 are 23 x 29

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

Given numbers are 390, 326, 771, 667

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

Apply this formula for all numbers.

Step1:

LCM(390, 326) = 63570

GCD(390, 326) = ( 390 x 326 ) / 63570

= 390 / 326

= 390

Step2:

LCM(2, 771) = 1542

GCD(2, 771) = ( 2 x 771 ) / 1542

= 2 / 771

= 2

Step3:

LCM(1, 667) = 667

GCD(1, 667) = ( 1 x 667 ) / 667

= 1 / 667

= 1

So, Greatest Common Divisor of 390, 326, 771, 667 is 1
