Lets's calculate LCM of 810,920
2 | 810, 920 |
5 | 405, 460 |
81, 92 |
∴ So the LCM of the given numbers is 2 x 5 x 81 x 92 = 74520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/74520
Therefore, the GCF of Fractions 470/810,343/920 is 1/74520
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 810,920 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(810,920) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(810,920) x common factors =10 x 1 = 10
LCM(810,920) = ( 810 × 920 ) / 10
LCM(810,920) = 745200 / 10
LCM(810,920) = 74520
