Given numbers are 438, 165, 343, 604

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 165 are 3 x 5 x 11

Prime factors of 343 are 7 x 7 x 7

Prime factors of 604 are 2 x 2 x 151

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

Given numbers are 438, 165, 343, 604

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

Apply this formula for all numbers.

Step1:

LCM(438, 165) = 24090

GCD(438, 165) = ( 438 x 165 ) / 24090

= 438 / 165

= 438

Step2:

LCM(3, 343) = 1029

GCD(3, 343) = ( 3 x 343 ) / 1029

= 3 / 343

= 3

Step3:

LCM(1, 604) = 604

GCD(1, 604) = ( 1 x 604 ) / 604

= 1 / 604

= 1

So, Greatest Common Divisor of 438, 165, 343, 604 is 1
