Greatest Common Divisior
We found the divisors of 642, 841, 841, 988 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 642, 841, 841, 988 is 1.
Therefore, GCD of numbers 642, 841, 841, 988 is 1
Given Input Data is 642, 841, 841, 988
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 642 is 2 x 3 x 107
Prime Factorization of 841 is 29 x 29
Prime Factorization of 841 is 29 x 29
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(642, 841) = 539922
GCD(642, 841) = ( 642 x 841 ) / 539922
GCD(642, 841) = 539922 / 539922
GCD(642, 841) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 841
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 841) = 841
GCD(1, 841) = ( 1 x 841 ) / 841
GCD(1, 841) = 841 / 841
GCD(1, 841) = 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 642, 841, 841, 988 is 1
