Given numbers are 838, 145, 645, 551

The list of prime factors of all numbers are

Prime factors of 838 are 2 x 419

Prime factors of 145 are 5 x 29

Prime factors of 645 are 3 x 5 x 43

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 838, 145, 645, 551

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

Apply this formula for all numbers.

Step1:

LCM(838, 145) = 121510

GCD(838, 145) = ( 838 x 145 ) / 121510

= 838 / 145

= 838

Step2:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

Step3:

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

= 1 / 551

= 1

So, Greatest Common Divisor of 838, 145, 645, 551 is 1
