Given numbers are 551, 644, 513, 461

The list of prime factors of all numbers are

Prime factors of 551 are 19 x 29

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 513 are 3 x 3 x 3 x 19

Prime factors of 461 are 461

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

Given numbers are 551, 644, 513, 461

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

Apply this formula for all numbers.

Step1:

LCM(551, 644) = 354844

GCD(551, 644) = ( 551 x 644 ) / 354844

= 551 / 644

= 551

Step2:

LCM(1, 513) = 513

GCD(1, 513) = ( 1 x 513 ) / 513

= 1 / 513

= 1

Step3:

LCM(1, 461) = 461

GCD(1, 461) = ( 1 x 461 ) / 461

= 1 / 461

= 1

So, Greatest Common Divisor of 551, 644, 513, 461 is 1
