Lets's calculate GCF of 245,665
5 | 245, 665 |
7 | 49, 133 |
7, 19 |
∴ So the GCF of the given numbers is 5 x 7 = 35
Now, list down the factors of 245
:1,5,7,35,49,245
Now, list down the factors of 665
:1,5,7,19,35,95,133,665
Greatest Common Factor
We found the factors 245,665 . The biggest common factor number is the GCF number.
So the greatest common factor 245,665 is 35.
Lets's calculate LCM of 814,851
37 | 814, 851 |
22, 23 |
∴ So the LCM of the given numbers is 37 x 22 x 23 = 18722
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 35/18722
Therefore, the GCF of Fractions 245/814,665/851 is 35/18722
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 814,851 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(814,851) = 37
common factors(in case of two or more numbers have common factors) = 1
GCF(814,851) x common factors =37 x 1 = 37
LCM(814,851) = ( 814 × 851 ) / 37
LCM(814,851) = 692714 / 37
LCM(814,851) = 18722
