Greatest Common Factor
We found the factors 144,387,455 . The biggest common factor number is the GCF number.
So the greatest common factor 144,387,455 is 1.
Lets's calculate LCM of 96,86,15
2 | 96, 86, 15 |
3 | 48, 43, 15 |
16, 43, 5 |
∴ So the LCM of the given numbers is 2 x 3 x 16 x 43 x 5 = 20640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/20640
Therefore, the GCF of Fractions 144/96,387/86,455/15 is 1/20640
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 96,86,15 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(96,86,15) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(96,86,15) x common factors =1 x 6 = 6
LCM(96,86,15) = ( 96 × 86 × 15 ) / 6
LCM(96,86,15) = 123840 / 6
LCM(96,86,15) = 20640
