Given numbers are 671, 665, 438, 306

The list of prime factors of all numbers are

Prime factors of 671 are 11 x 61

Prime factors of 665 are 5 x 7 x 19

Prime factors of 438 are 2 x 3 x 73

Prime factors of 306 are 2 x 3 x 3 x 17

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

Given numbers are 671, 665, 438, 306

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

Apply this formula for all numbers.

Step1:

LCM(671, 665) = 446215

GCD(671, 665) = ( 671 x 665 ) / 446215

= 671 / 665

= 671

Step2:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

Step3:

LCM(1, 306) = 306

GCD(1, 306) = ( 1 x 306 ) / 306

= 1 / 306

= 1

So, Greatest Common Divisor of 671, 665, 438, 306 is 1
