Given numbers are 128, 551, 396, 347

The list of prime factors of all numbers are

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 551 are 19 x 29

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 347 are 347

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

Given numbers are 128, 551, 396, 347

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

Apply this formula for all numbers.

Step1:

LCM(128, 551) = 70528

GCD(128, 551) = ( 128 x 551 ) / 70528

= 128 / 551

= 128

Step2:

LCM(1, 396) = 396

GCD(1, 396) = ( 1 x 396 ) / 396

= 1 / 396

= 1

Step3:

LCM(1, 347) = 347

GCD(1, 347) = ( 1 x 347 ) / 347

= 1 / 347

= 1

So, Greatest Common Divisor of 128, 551, 396, 347 is 1
