Given numbers are 783, 390, 344, 478

The list of prime factors of all numbers are

Prime factors of 783 are 3 x 3 x 3 x 29

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

Prime factors of 344 are 2 x 2 x 2 x 43

Prime factors of 478 are 2 x 239

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

Given numbers are 783, 390, 344, 478

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

Apply this formula for all numbers.

Step1:

LCM(783, 390) = 101790

GCD(783, 390) = ( 783 x 390 ) / 101790

= 783 / 390

= 783

Step2:

LCM(3, 344) = 1032

GCD(3, 344) = ( 3 x 344 ) / 1032

= 3 / 344

= 3

Step3:

LCM(1, 478) = 478

GCD(1, 478) = ( 1 x 478 ) / 478

= 1 / 478

= 1

So, Greatest Common Divisor of 783, 390, 344, 478 is 1
