Given numbers are 390, 350, 423, 538

The list of prime factors of all numbers are

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

Prime factors of 350 are 2 x 5 x 5 x 7

Prime factors of 423 are 3 x 3 x 47

Prime factors of 538 are 2 x 269

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

Given numbers are 390, 350, 423, 538

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

Apply this formula for all numbers.

Step1:

LCM(390, 350) = 13650

GCD(390, 350) = ( 390 x 350 ) / 13650

= 390 / 350

= 390

Step2:

LCM(10, 423) = 4230

GCD(10, 423) = ( 10 x 423 ) / 4230

= 10 / 423

= 10

Step3:

LCM(1, 538) = 538

GCD(1, 538) = ( 1 x 538 ) / 538

= 1 / 538

= 1

So, Greatest Common Divisor of 390, 350, 423, 538 is 1
