Lets's calculate LCM of 612,810
2 | 612, 810 |
3 | 306, 405 |
3 | 102, 135 |
34, 45 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 34 x 45 = 27540
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/27540
Therefore, the GCF of Fractions 980/612,212/810 is 4/27540
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 612,810 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(612,810) = 18
common factors(in case of two or more numbers have common factors) = 1
GCF(612,810) x common factors =18 x 1 = 18
LCM(612,810) = ( 612 × 810 ) / 18
LCM(612,810) = 495720 / 18
LCM(612,810) = 27540
