Greatest Common Factor
We found the factors 54,234,689 . The biggest common factor number is the GCF number.
So the greatest common factor 54,234,689 is 1.
Lets's calculate LCM of 39,12,342
2 | 39, 12, 342 |
3 | 39, 6, 171 |
13, 2, 57 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 2 x 57 = 8892
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/8892
Therefore, the GCF of Fractions 54/39,234/12,689/342 is 1/8892
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 39,12,342 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,12,342) = 3
common factors(in case of two or more numbers have common factors) = 6
GCF(39,12,342) x common factors =3 x 6 = 18
LCM(39,12,342) = ( 39 × 12 × 342 ) / 18
LCM(39,12,342) = 160056 / 18
LCM(39,12,342) = 8892
