Greatest Common Divisior
We found the divisors of 310, 891, 63, 988 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 310, 891, 63, 988 is 1.
Therefore, GCD of numbers 310, 891, 63, 988 is 1
Given Input Data is 310, 891, 63, 988
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 310 is 2 x 5 x 31
Prime Factorization of 891 is 3 x 3 x 3 x 3 x 11
Prime Factorization of 63 is 3 x 3 x 7
Prime Factorization of 988 is 2 x 2 x 13 x 19
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(310, 891) = 276210
GCD(310, 891) = ( 310 x 891 ) / 276210
GCD(310, 891) = 276210 / 276210
GCD(310, 891) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 63
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 63) = 63
GCD(1, 63) = ( 1 x 63 ) / 63
GCD(1, 63) = 63 / 63
GCD(1, 63) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 988
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 988) = 988
GCD(1, 988) = ( 1 x 988 ) / 988
GCD(1, 988) = 988 / 988
GCD(1, 988) = 1
GCD of 310, 891, 63, 988 is 1
