Lets's calculate LCM of 290,815
5 | 290, 815 |
58, 163 |
∴ So the LCM of the given numbers is 5 x 58 x 163 = 47270
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/47270
Therefore, the GCF of Fractions 626/290,990/815 is 2/47270
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 290,815 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(290,815) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(290,815) x common factors =5 x 1 = 5
LCM(290,815) = ( 290 × 815 ) / 5
LCM(290,815) = 236350 / 5
LCM(290,815) = 47270
