Greatest Common Factor
We found the factors 68,147,989 . The biggest common factor number is the GCF number.
So the greatest common factor 68,147,989 is 1.
Lets's calculate LCM of 95,71,120
5 | 95, 71, 120 |
19, 71, 24 |
∴ So the LCM of the given numbers is 5 x 19 x 71 x 24 = 161880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/161880
Therefore, the GCF of Fractions 68/95,147/71,989/120 is 1/161880
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 95,71,120 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(95,71,120) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(95,71,120) x common factors =1 x 5 = 5
LCM(95,71,120) = ( 95 × 71 × 120 ) / 5
LCM(95,71,120) = 809400 / 5
LCM(95,71,120) = 161880
