Greatest Common Divisior
We found the divisors of 942, 247, 821, 454 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 942, 247, 821, 454 is 1.
Therefore, GCD of numbers 942, 247, 821, 454 is 1
Given Input Data is 942, 247, 821, 454
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 942 is 2 x 3 x 157
Prime Factorization of 247 is 13 x 19
Prime Factorization of 821 is 821
Prime Factorization of 454 is 2 x 227
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(942, 247) = 232674
GCD(942, 247) = ( 942 x 247 ) / 232674
GCD(942, 247) = 232674 / 232674
GCD(942, 247) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 821
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 821) = 821
GCD(1, 821) = ( 1 x 821 ) / 821
GCD(1, 821) = 821 / 821
GCD(1, 821) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 454
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 454) = 454
GCD(1, 454) = ( 1 x 454 ) / 454
GCD(1, 454) = 454 / 454
GCD(1, 454) = 1
GCD of 942, 247, 821, 454 is 1
