Lets's calculate LCM of 290,840
2 | 290, 840 |
5 | 145, 420 |
29, 84 |
∴ So the LCM of the given numbers is 2 x 5 x 29 x 84 = 24360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 26/24360
Therefore, the GCF of Fractions 858/290,1118/840 is 26/24360
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 290,840 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(290,840) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(290,840) x common factors =10 x 1 = 10
LCM(290,840) = ( 290 × 840 ) / 10
LCM(290,840) = 243600 / 10
LCM(290,840) = 24360
