Given numbers are 390, 790, 659, 478

The list of prime factors of all numbers are

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

Prime factors of 790 are 2 x 5 x 79

Prime factors of 659 are 659

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 390, 790, 659, 478

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

Apply this formula for all numbers.

Step1:

LCM(390, 790) = 30810

GCD(390, 790) = ( 390 x 790 ) / 30810

= 390 / 790

= 390

Step2:

LCM(10, 659) = 6590

GCD(10, 659) = ( 10 x 659 ) / 6590

= 10 / 659

= 10

Step3:

LCM(1, 478) = 478

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

= 1 / 478

= 1

So, Greatest Common Divisor of 390, 790, 659, 478 is 1
