Given numbers are 438, 336, 255, 154

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 336 are 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 255 are 3 x 5 x 17

Prime factors of 154 are 2 x 7 x 11

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

Given numbers are 438, 336, 255, 154

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

Apply this formula for all numbers.

Step1:

LCM(438, 336) = 24528

GCD(438, 336) = ( 438 x 336 ) / 24528

= 438 / 336

= 438

Step2:

LCM(6, 255) = 510

GCD(6, 255) = ( 6 x 255 ) / 510

= 6 / 255

= 6

Step3:

LCM(3, 154) = 462

GCD(3, 154) = ( 3 x 154 ) / 462

= 3 / 154

= 3

So, Greatest Common Divisor of 438, 336, 255, 154 is 1
