Given numbers are 551, 678, 419, 816

The list of prime factors of all numbers are

Prime factors of 551 are 19 x 29

Prime factors of 678 are 2 x 3 x 113

Prime factors of 419 are 419

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

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

Given numbers are 551, 678, 419, 816

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

Apply this formula for all numbers.

Step1:

LCM(551, 678) = 373578

GCD(551, 678) = ( 551 x 678 ) / 373578

= 551 / 678

= 551

Step2:

LCM(1, 419) = 419

GCD(1, 419) = ( 1 x 419 ) / 419

= 1 / 419

= 1

Step3:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

So, Greatest Common Divisor of 551, 678, 419, 816 is 1
