Given numbers are 438, 745, 671, 684

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 745 are 5 x 149

Prime factors of 671 are 11 x 61

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

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

Given numbers are 438, 745, 671, 684

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

Apply this formula for all numbers.

Step1:

LCM(438, 745) = 326310

GCD(438, 745) = ( 438 x 745 ) / 326310

= 438 / 745

= 438

Step2:

LCM(1, 671) = 671

GCD(1, 671) = ( 1 x 671 ) / 671

= 1 / 671

= 1

Step3:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

So, Greatest Common Divisor of 438, 745, 671, 684 is 1
