Given numbers are 143, 438, 321, 612

The list of prime factors of all numbers are

Prime factors of 143 are 11 x 13

Prime factors of 438 are 2 x 3 x 73

Prime factors of 321 are 3 x 107

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

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

Given numbers are 143, 438, 321, 612

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

Apply this formula for all numbers.

Step1:

LCM(143, 438) = 62634

GCD(143, 438) = ( 143 x 438 ) / 62634

= 143 / 438

= 143

Step2:

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

= 1 / 321

= 1

Step3:

LCM(1, 612) = 612

GCD(1, 612) = ( 1 x 612 ) / 612

= 1 / 612

= 1

So, Greatest Common Divisor of 143, 438, 321, 612 is 1
