Greatest Common Divisior
We found the divisors of 981, 754, 21, 248 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 981, 754, 21, 248 is 1.
Therefore, GCD of numbers 981, 754, 21, 248 is 1
Given Input Data is 981, 754, 21, 248
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 981 is 3 x 3 x 109
Prime Factorization of 754 is 2 x 13 x 29
Prime Factorization of 21 is 3 x 7
Prime Factorization of 248 is 2 x 2 x 2 x 31
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(981, 754) = 739674
GCD(981, 754) = ( 981 x 754 ) / 739674
GCD(981, 754) = 739674 / 739674
GCD(981, 754) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 21
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 21) = 21
GCD(1, 21) = ( 1 x 21 ) / 21
GCD(1, 21) = 21 / 21
GCD(1, 21) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 248
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 248) = 248
GCD(1, 248) = ( 1 x 248 ) / 248
GCD(1, 248) = 248 / 248
GCD(1, 248) = 1
GCD of 981, 754, 21, 248 is 1
