Greatest Common Factor
We found the factors 480,111 . The biggest common factor number is the GCF number.
So the greatest common factor 480,111 is 3.
Lets's calculate LCM of 381,147
3 | 381, 147 |
127, 49 |
∴ So the LCM of the given numbers is 3 x 127 x 49 = 18669
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/18669
Therefore, the GCF of Fractions 480/381,111/147 is 3/18669
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 381,147 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(381,147) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(381,147) x common factors =3 x 1 = 3
LCM(381,147) = ( 381 × 147 ) / 3
LCM(381,147) = 56007 / 3
LCM(381,147) = 18669
