Greatest Common Divisior
We found the divisors of 991, 661, 838, 276 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 991, 661, 838, 276 is 1.
Therefore, GCD of numbers 991, 661, 838, 276 is 1
Given Input Data is 991, 661, 838, 276
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 991 is 991
Prime Factorization of 661 is 661
Prime Factorization of 838 is 2 x 419
Prime Factorization of 276 is 2 x 2 x 3 x 23
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(991, 661) = 655051
GCD(991, 661) = ( 991 x 661 ) / 655051
GCD(991, 661) = 655051 / 655051
GCD(991, 661) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 838
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 838) = 838
GCD(1, 838) = ( 1 x 838 ) / 838
GCD(1, 838) = 838 / 838
GCD(1, 838) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 276
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 276) = 276
GCD(1, 276) = ( 1 x 276 ) / 276
GCD(1, 276) = 276 / 276
GCD(1, 276) = 1
GCD of 991, 661, 838, 276 is 1
