Greatest Common Divisior
We found the divisors of 623, 486, 309, 147 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 623, 486, 309, 147 is 1.
Therefore, GCD of numbers 623, 486, 309, 147 is 1
Given Input Data is 623, 486, 309, 147
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 623 is 7 x 89
Prime Factorization of 486 is 2 x 3 x 3 x 3 x 3 x 3
Prime Factorization of 309 is 3 x 103
Prime Factorization of 147 is 3 x 7 x 7
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(623, 486) = 302778
GCD(623, 486) = ( 623 x 486 ) / 302778
GCD(623, 486) = 302778 / 302778
GCD(623, 486) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 309
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
GCD(1, 309) = 309 / 309
GCD(1, 309) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 147
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 147) = 147
GCD(1, 147) = ( 1 x 147 ) / 147
GCD(1, 147) = 147 / 147
GCD(1, 147) = 1
GCD of 623, 486, 309, 147 is 1
