Greatest Common Factor
We found the factors 99,81,255 . The biggest common factor number is the GCF number.
So the greatest common factor 99,81,255 is 3.
Lets's calculate LCM of 15,550,144
2 | 15, 550, 144 |
3 | 15, 275, 72 |
5 | 5, 275, 24 |
1, 55, 24 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 1 x 55 x 24 = 39600
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/39600
Therefore, the GCF of Fractions 99/15,81/550,255/144 is 3/39600
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 15,550,144 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,550,144) = 1
common factors(in case of two or more numbers have common factors) = 30
GCF(15,550,144) x common factors =1 x 30 = 30
LCM(15,550,144) = ( 15 × 550 × 144 ) / 30
LCM(15,550,144) = 1188000 / 30
LCM(15,550,144) = 39600
