We found the factors 783,540 . The biggest common factor number is the GCF number.
So the greatest common factor 783,540 is 27.
Lets's calculate LCM of 490,110
2 | 490, 110 |
5 | 245, 55 |
49, 11 |
∴ So the LCM of the given numbers is 2 x 5 x 49 x 11 = 5390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 27/5390
Therefore, the GCF of Fractions 783/490,540/110 is 27/5390
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 490,110 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(490,110) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(490,110) x common factors =10 x 1 = 10
LCM(490,110) = ( 490 × 110 ) / 10
LCM(490,110) = 53900 / 10
LCM(490,110) = 5390
