Greatest Common Factor
We found the factors 216,281 . The biggest common factor number is the GCF number.
So the greatest common factor 216,281 is 1.
Lets's calculate LCM of 305,765
5 | 305, 765 |
61, 153 |
∴ So the LCM of the given numbers is 5 x 61 x 153 = 46665
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/46665
Therefore, the GCF of Fractions 216/305,281/765 is 1/46665
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 305,765 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(305,765) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(305,765) x common factors =5 x 1 = 5
LCM(305,765) = ( 305 × 765 ) / 5
LCM(305,765) = 233325 / 5
LCM(305,765) = 46665
