Given numbers are 399, 782, 770, 424

The list of prime factors of all numbers are

Prime factors of 399 are 3 x 7 x 19

Prime factors of 782 are 2 x 17 x 23

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 424 are 2 x 2 x 2 x 53

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

Given numbers are 399, 782, 770, 424

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

Apply this formula for all numbers.

Step1:

LCM(399, 782) = 312018

GCD(399, 782) = ( 399 x 782 ) / 312018

= 399 / 782

= 399

Step2:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

Step3:

LCM(1, 424) = 424

GCD(1, 424) = ( 1 x 424 ) / 424

= 1 / 424

= 1

So, Greatest Common Divisor of 399, 782, 770, 424 is 1
