Given numbers are 518, 835, 390, 920

The list of prime factors of all numbers are

Prime factors of 518 are 2 x 7 x 37

Prime factors of 835 are 5 x 167

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

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

Given numbers are 518, 835, 390, 920

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

Apply this formula for all numbers.

Step1:

LCM(518, 835) = 432530

GCD(518, 835) = ( 518 x 835 ) / 432530

= 518 / 835

= 518

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

So, Greatest Common Divisor of 518, 835, 390, 920 is 1
