So the greatest common factor 907,689 is 1.
Lets's calculate LCM of 402,141
3 | 402, 141 |
134, 47 |
∴ So the LCM of the given numbers is 3 x 134 x 47 = 18894
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/18894
Therefore, the GCF of Fractions 907/402,689/141 is 1/18894
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 402,141 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(402,141) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(402,141) x common factors =3 x 1 = 3
LCM(402,141) = ( 402 × 141 ) / 3
LCM(402,141) = 56682 / 3
LCM(402,141) = 18894
