1, 3, 317, 951
Greatest Common Divisior
We found the divisors of 621, 480, 821, 951 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 621, 480, 821, 951 is 1.
Therefore, GCD of numbers 621, 480, 821, 951 is 1
Given Input Data is 621, 480, 821, 951
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 621 is 3 x 3 x 3 x 23
Prime Factorization of 480 is 2 x 2 x 2 x 2 x 2 x 3 x 5
Prime Factorization of 821 is 821
Prime Factorization of 951 is 3 x 317
The above numbers do not have any common prime factor. So GCD is 1
Step1:
Let's calculate the GCD of first two numbers
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(621, 480) = 99360
GCD(621, 480) = ( 621 x 480 ) / 99360
GCD(621, 480) = 298080 / 99360
GCD(621, 480) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 821
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 821) = 2463
GCD(3, 821) = ( 3 x 821 ) / 2463
GCD(3, 821) = 2463 / 2463
GCD(3, 821) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 951
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 951) = 951
GCD(1, 951) = ( 1 x 951 ) / 951
GCD(1, 951) = 951 / 951
GCD(1, 951) = 1
GCD of 621, 480, 821, 951 is 1
