Greatest Common Factor
We found the factors 752,254,991 . The biggest common factor number is the GCF number.
So the greatest common factor 752,254,991 is 1.
Lets's calculate LCM of 99,45,12
3 | 99, 45, 12 |
3 | 33, 15, 4 |
11, 5, 4 |
∴ So the LCM of the given numbers is 3 x 3 x 11 x 5 x 4 = 1980
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1980
Therefore, the GCF of Fractions 752/99,254/45,991/12 is 1/1980
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 99,45,12 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(99,45,12) = 3
common factors(in case of two or more numbers have common factors) = 9
GCF(99,45,12) x common factors =3 x 9 = 27
LCM(99,45,12) = ( 99 × 45 × 12 ) / 27
LCM(99,45,12) = 53460 / 27
LCM(99,45,12) = 1980
