Greatest Common Factor
We found the factors 542,202,405 . The biggest common factor number is the GCF number.
So the greatest common factor 542,202,405 is 1.
Lets's calculate LCM of 55,90,132
| 2 | 55, 90, 132 |
| 3 | 55, 45, 66 |
| 5 | 55, 15, 22 |
| 11 | 11, 3, 22 |
| 1, 3, 2 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 11 x 1 x 3 x 2 = 1980
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1980
Therefore, the GCF of Fractions 542/55,202/90,405/132 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 55,90,132 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(55,90,132) = 1
common factors(in case of two or more numbers have common factors) = 330
GCF(55,90,132) x common factors =1 x 330 = 330
LCM(55,90,132) = ( 55 × 90 × 132 ) / 330
LCM(55,90,132) = 653400 / 330
LCM(55,90,132) = 1980
