Greatest Common Factor
We found the factors 21,35,48,82 . The biggest common factor number is the GCF number.
So the greatest common factor 21,35,48,82 is 1.
Lets's calculate LCM of 48,96,75,60
2 | 48, 96, 75, 60 |
2 | 24, 48, 75, 30 |
2 | 12, 24, 75, 15 |
2 | 6, 12, 75, 15 |
3 | 3, 6, 75, 15 |
5 | 1, 2, 25, 5 |
1, 2, 1, 5 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 3 x 5 x 1 x 2 x 1 x 5 = 2400
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2400
Therefore, the GCF of Fractions 21/48,35/96,48/75,82/60 is 1/2400
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 48,96,75,60 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(48,96,75,60) = 3
common factors(in case of two or more numbers have common factors) = 2880
GCF(48,96,75,60) x common factors =3 x 2880 = 8640
LCM(48,96,75,60) = ( 48 × 96 × 75 × 60 ) / 8640
LCM(48,96,75,60) = 20736000 / 8640
LCM(48,96,75,60) = 2400
