So the greatest common factor 255,573,841 is 1.
Lets's calculate LCM of 270,393,915
3 | 270, 393, 915 |
5 | 90, 131, 305 |
18, 131, 61 |
∴ So the LCM of the given numbers is 3 x 5 x 18 x 131 x 61 = 2157570
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2157570
Therefore, the GCF of Fractions 255/270,573/393,841/915 is 1/2157570
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 270,393,915 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(270,393,915) = 3
common factors(in case of two or more numbers have common factors) = 15
GCF(270,393,915) x common factors =3 x 15 = 45
LCM(270,393,915) = ( 270 × 393 × 915 ) / 45
LCM(270,393,915) = 97090650 / 45
LCM(270,393,915) = 2157570
