Lets's calculate LCM of 502,838
2 | 502, 838 |
251, 419 |
∴ So the LCM of the given numbers is 2 x 251 x 419 = 210338
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 22/210338
Therefore, the GCF of Fractions 154/502,7040/838 is 22/210338
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 502,838 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(502,838) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(502,838) x common factors =2 x 1 = 2
LCM(502,838) = ( 502 × 838 ) / 2
LCM(502,838) = 420676 / 2
LCM(502,838) = 210338
