Given numbers are 438, 423, 385, 542

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 423 are 3 x 3 x 47

Prime factors of 385 are 5 x 7 x 11

Prime factors of 542 are 2 x 271

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

Given numbers are 438, 423, 385, 542

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

Apply this formula for all numbers.

Step1:

LCM(438, 423) = 61758

GCD(438, 423) = ( 438 x 423 ) / 61758

= 438 / 423

= 438

Step2:

LCM(3, 385) = 1155

GCD(3, 385) = ( 3 x 385 ) / 1155

= 3 / 385

= 3

Step3:

LCM(1, 542) = 542

GCD(1, 542) = ( 1 x 542 ) / 542

= 1 / 542

= 1

So, Greatest Common Divisor of 438, 423, 385, 542 is 1
