So the greatest common factor 409,385 is 1.
Lets's calculate LCM of 948,801
3 | 948, 801 |
316, 267 |
∴ So the LCM of the given numbers is 3 x 316 x 267 = 253116
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/253116
Therefore, the GCF of Fractions 409/948,385/801 is 1/253116
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 948,801 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(948,801) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(948,801) x common factors =3 x 1 = 3
LCM(948,801) = ( 948 × 801 ) / 3
LCM(948,801) = 759348 / 3
LCM(948,801) = 253116
