So the greatest common factor 436,398 is 2.
Lets's calculate LCM of 909,732
3 | 909, 732 |
303, 244 |
∴ So the LCM of the given numbers is 3 x 303 x 244 = 221796
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/221796
Therefore, the GCF of Fractions 436/909,398/732 is 2/221796
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 909,732 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(909,732) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(909,732) x common factors =3 x 1 = 3
LCM(909,732) = ( 909 × 732 ) / 3
LCM(909,732) = 665388 / 3
LCM(909,732) = 221796
