Given numbers are 438, 304, 386, 551

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 304 are 2 x 2 x 2 x 2 x 19

Prime factors of 386 are 2 x 193

Prime factors of 551 are 19 x 29

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

Given numbers are 438, 304, 386, 551

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

Apply this formula for all numbers.

Step1:

LCM(438, 304) = 66576

GCD(438, 304) = ( 438 x 304 ) / 66576

= 438 / 304

= 438

Step2:

LCM(2, 386) = 386

GCD(2, 386) = ( 2 x 386 ) / 386

= 2 / 386

= 2

Step3:

LCM(2, 551) = 1102

GCD(2, 551) = ( 2 x 551 ) / 1102

= 2 / 551

= 2

So, Greatest Common Divisor of 438, 304, 386, 551 is 1
