Greatest Common Factor
We found the factors 43,35,455 . The biggest common factor number is the GCF number.
So the greatest common factor 43,35,455 is 1.
Lets's calculate LCM of 890,200,215
2 | 890, 200, 215 |
5 | 445, 100, 215 |
89, 20, 43 |
∴ So the LCM of the given numbers is 2 x 5 x 89 x 20 x 43 = 765400
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/765400
Therefore, the GCF of Fractions 43/890,35/200,455/215 is 1/765400
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 890,200,215 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(890,200,215) = 5
common factors(in case of two or more numbers have common factors) = 10
GCF(890,200,215) x common factors =5 x 10 = 50
LCM(890,200,215) = ( 890 × 200 × 215 ) / 50
LCM(890,200,215) = 38270000 / 50
LCM(890,200,215) = 765400
