Lets's calculate GCF of 254,315
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 254
:1,2,127,254
Now, list down the factors of 315
:1,3,5,7,9,15,21,35,45,63,105,315
Greatest Common Factor
We found the factors 254,315 . The biggest common factor number is the GCF number.
So the greatest common factor 254,315 is 1.
Lets's calculate LCM of 90,795
3 | 90, 795 |
5 | 30, 265 |
6, 53 |
∴ So the LCM of the given numbers is 3 x 5 x 6 x 53 = 4770
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4770
Therefore, the GCF of Fractions 254/90,315/795 is 1/4770
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 90,795 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,795) = 15
common factors(in case of two or more numbers have common factors) = 1
GCF(90,795) x common factors =15 x 1 = 15
LCM(90,795) = ( 90 × 795 ) / 15
LCM(90,795) = 71550 / 15
LCM(90,795) = 4770
