Greatest Common Factor
We found the factors 170,911 . The biggest common factor number is the GCF number.
So the greatest common factor 170,911 is 1.
Lets's calculate LCM of 288,782
2 | 288, 782 |
144, 391 |
∴ So the LCM of the given numbers is 2 x 144 x 391 = 112608
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/112608
Therefore, the GCF of Fractions 170/288,911/782 is 1/112608
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 288,782 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(288,782) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(288,782) x common factors =2 x 1 = 2
LCM(288,782) = ( 288 × 782 ) / 2
LCM(288,782) = 225216 / 2
LCM(288,782) = 112608
