Greatest Common Factor
We found the factors 39,253,154 . The biggest common factor number is the GCF number.
So the greatest common factor 39,253,154 is 1.
Lets's calculate LCM of 90,99,488
2 | 90, 99, 488 |
3 | 45, 99, 244 |
3 | 15, 33, 244 |
5, 11, 244 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 11 x 244 = 241560
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/241560
Therefore, the GCF of Fractions 39/90,253/99,154/488 is 1/241560
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 90,99,488 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,99,488) = 1
common factors(in case of two or more numbers have common factors) = 18
GCF(90,99,488) x common factors =1 x 18 = 18
LCM(90,99,488) = ( 90 × 99 × 488 ) / 18
LCM(90,99,488) = 4348080 / 18
LCM(90,99,488) = 241560
