Given numbers are 551, 738, 420, 311

The list of prime factors of all numbers are

Prime factors of 551 are 19 x 29

Prime factors of 738 are 2 x 3 x 3 x 41

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 311 are 311

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

Given numbers are 551, 738, 420, 311

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

Apply this formula for all numbers.

Step1:

LCM(551, 738) = 406638

GCD(551, 738) = ( 551 x 738 ) / 406638

= 551 / 738

= 551

Step2:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

Step3:

LCM(1, 311) = 311

GCD(1, 311) = ( 1 x 311 ) / 311

= 1 / 311

= 1

So, Greatest Common Divisor of 551, 738, 420, 311 is 1
