Given numbers are 438, 164, 758, 747

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 164 are 2 x 2 x 41

Prime factors of 758 are 2 x 379

Prime factors of 747 are 3 x 3 x 83

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

Given numbers are 438, 164, 758, 747

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

Apply this formula for all numbers.

Step1:

LCM(438, 164) = 35916

GCD(438, 164) = ( 438 x 164 ) / 35916

= 438 / 164

= 438

Step2:

LCM(2, 758) = 758

GCD(2, 758) = ( 2 x 758 ) / 758

= 2 / 758

= 2

Step3:

LCM(2, 747) = 1494

GCD(2, 747) = ( 2 x 747 ) / 1494

= 2 / 747

= 2

So, Greatest Common Divisor of 438, 164, 758, 747 is 1
