5 | 35, 35 |
7 | 7, 7 |
1, 1 |
∴ So the GCF of the given numbers is 3 x 3 x 3 x 5 x 7 = 945
Now, list down the factors of 945
:1,3,5,7,9,15,21,27,35,45,63,105,135,189,315,945
Now, list down the factors of 945
:1,3,5,7,9,15,21,27,35,45,63,105,135,189,315,945
Greatest Common Factor
We found the factors 945,945 . The biggest common factor number is the GCF number.
So the greatest common factor 945,945 is 945.
Lets's calculate LCM of 702,418
2 | 702, 418 |
351, 209 |
∴ So the LCM of the given numbers is 2 x 351 x 209 = 146718
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 945/146718
Therefore, the GCF of Fractions 945/702,945/418 is 945/146718
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 702,418 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(702,418) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(702,418) x common factors =2 x 1 = 2
LCM(702,418) = ( 702 × 418 ) / 2
LCM(702,418) = 293436 / 2
LCM(702,418) = 146718
