Given numbers are 551, 420, 370, 491

The list of prime factors of all numbers are

Prime factors of 551 are 19 x 29

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

Prime factors of 370 are 2 x 5 x 37

Prime factors of 491 are 491

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

Given numbers are 551, 420, 370, 491

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

Apply this formula for all numbers.

Step1:

LCM(551, 420) = 231420

GCD(551, 420) = ( 551 x 420 ) / 231420

= 551 / 420

= 551

Step2:

LCM(1, 370) = 370

GCD(1, 370) = ( 1 x 370 ) / 370

= 1 / 370

= 1

Step3:

LCM(1, 491) = 491

GCD(1, 491) = ( 1 x 491 ) / 491

= 1 / 491

= 1

So, Greatest Common Divisor of 551, 420, 370, 491 is 1
