Greatest Common Factor
We found the factors 380,570 . The biggest common factor number is the GCF number.
So the greatest common factor 380,570 is 190.
Lets's calculate LCM of 806,290
2 | 806, 290 |
403, 145 |
∴ So the LCM of the given numbers is 2 x 403 x 145 = 116870
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 190/116870
Therefore, the GCF of Fractions 380/806,570/290 is 190/116870
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 806,290 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(806,290) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(806,290) x common factors =2 x 1 = 2
LCM(806,290) = ( 806 × 290 ) / 2
LCM(806,290) = 233740 / 2
LCM(806,290) = 116870
