Greatest Common Factor
We found the factors 60,67,643 . The biggest common factor number is the GCF number.
So the greatest common factor 60,67,643 is 1.
Lets's calculate LCM of 10,90,15
2 | 10, 90, 15 |
3 | 5, 45, 15 |
5 | 5, 5, 15 |
1, 1, 3 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 1 x 1 x 3 = 90
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/90
Therefore, the GCF of Fractions 60/10,67/90,643/15 is 1/90
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 10,90,15 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(10,90,15) = 5
common factors(in case of two or more numbers have common factors) = 30
GCF(10,90,15) x common factors =5 x 30 = 150
LCM(10,90,15) = ( 10 × 90 × 15 ) / 150
LCM(10,90,15) = 13500 / 150
LCM(10,90,15) = 90
