Greatest Common Factor
We found the factors 49,63,930 . The biggest common factor number is the GCF number.
So the greatest common factor 49,63,930 is 1.
Lets's calculate LCM of 30,95,90
2 | 30, 95, 90 |
3 | 15, 95, 45 |
5 | 5, 95, 15 |
1, 19, 3 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 1 x 19 x 3 = 1710
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1710
Therefore, the GCF of Fractions 49/30,63/95,930/90 is 1/1710
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 30,95,90 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,95,90) = 5
common factors(in case of two or more numbers have common factors) = 30
GCF(30,95,90) x common factors =5 x 30 = 150
LCM(30,95,90) = ( 30 × 95 × 90 ) / 150
LCM(30,95,90) = 256500 / 150
LCM(30,95,90) = 1710
