Given numbers are 438, 225, 233, 243

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 225 are 3 x 3 x 5 x 5

Prime factors of 233 are 233

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

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

Given numbers are 438, 225, 233, 243

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

Apply this formula for all numbers.

Step1:

LCM(438, 225) = 32850

GCD(438, 225) = ( 438 x 225 ) / 32850

= 438 / 225

= 438

Step2:

LCM(3, 233) = 699

GCD(3, 233) = ( 3 x 233 ) / 699

= 3 / 233

= 3

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 438, 225, 233, 243 is 1
