Greatest Common Factor
We found the factors 855,573 . The biggest common factor number is the GCF number.
So the greatest common factor 855,573 is 3.
Lets's calculate LCM of 213,258
3 | 213, 258 |
71, 86 |
∴ So the LCM of the given numbers is 3 x 71 x 86 = 18318
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/18318
Therefore, the GCF of Fractions 855/213,573/258 is 3/18318
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 213,258 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(213,258) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(213,258) x common factors =3 x 1 = 3
LCM(213,258) = ( 213 × 258 ) / 3
LCM(213,258) = 54954 / 3
LCM(213,258) = 18318
