Given numbers are 390, 920, 449, 851

The list of prime factors of all numbers are

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

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 449 are 449

Prime factors of 851 are 23 x 37

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

Given numbers are 390, 920, 449, 851

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

Apply this formula for all numbers.

Step1:

LCM(390, 920) = 35880

GCD(390, 920) = ( 390 x 920 ) / 35880

= 390 / 920

= 390

Step2:

LCM(10, 449) = 4490

GCD(10, 449) = ( 10 x 449 ) / 4490

= 10 / 449

= 10

Step3:

LCM(1, 851) = 851

GCD(1, 851) = ( 1 x 851 ) / 851

= 1 / 851

= 1

So, Greatest Common Divisor of 390, 920, 449, 851 is 1
