So the greatest common factor 562,432 is 2.
Lets's calculate LCM of 420,309
3 | 420, 309 |
140, 103 |
∴ So the LCM of the given numbers is 3 x 140 x 103 = 43260
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/43260
Therefore, the GCF of Fractions 562/420,432/309 is 2/43260
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 420,309 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,309) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(420,309) x common factors =3 x 1 = 3
LCM(420,309) = ( 420 × 309 ) / 3
LCM(420,309) = 129780 / 3
LCM(420,309) = 43260
