Given numbers are 438, 670, 437, 204

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 670 are 2 x 5 x 67

Prime factors of 437 are 19 x 23

Prime factors of 204 are 2 x 2 x 3 x 17

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

Given numbers are 438, 670, 437, 204

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

Apply this formula for all numbers.

Step1:

LCM(438, 670) = 146730

GCD(438, 670) = ( 438 x 670 ) / 146730

= 438 / 670

= 438

Step2:

LCM(2, 437) = 874

GCD(2, 437) = ( 2 x 437 ) / 874

= 2 / 437

= 2

Step3:

LCM(1, 204) = 204

GCD(1, 204) = ( 1 x 204 ) / 204

= 1 / 204

= 1

So, Greatest Common Divisor of 438, 670, 437, 204 is 1
