Lets's calculate LCM of 270,1410
2 | 270, 1410 |
3 | 135, 705 |
5 | 45, 235 |
9, 47 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 9 x 47 = 12690
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/12690
Therefore, the GCF of Fractions 2730/270,8475/1410 is 15/12690
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 270,1410 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(270,1410) = 30
common factors(in case of two or more numbers have common factors) = 1
GCF(270,1410) x common factors =30 x 1 = 30
LCM(270,1410) = ( 270 × 1410 ) / 30
LCM(270,1410) = 380700 / 30
LCM(270,1410) = 12690
