Greatest Common Factor
We found the factors 231,437 . The biggest common factor number is the GCF number.
So the greatest common factor 231,437 is 1.
Lets's calculate LCM of 453,270
3 | 453, 270 |
151, 90 |
∴ So the LCM of the given numbers is 3 x 151 x 90 = 40770
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/40770
Therefore, the GCF of Fractions 231/453,437/270 is 1/40770
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 453,270 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(453,270) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(453,270) x common factors =3 x 1 = 3
LCM(453,270) = ( 453 × 270 ) / 3
LCM(453,270) = 122310 / 3
LCM(453,270) = 40770
