Greatest Common Factor
We found the factors 240,171 . The biggest common factor number is the GCF number.
So the greatest common factor 240,171 is 3.
Lets's calculate LCM of 805,938
7 | 805, 938 |
115, 134 |
∴ So the LCM of the given numbers is 7 x 115 x 134 = 107870
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/107870
Therefore, the GCF of Fractions 240/805,171/938 is 3/107870
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 805,938 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(805,938) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(805,938) x common factors =7 x 1 = 7
LCM(805,938) = ( 805 × 938 ) / 7
LCM(805,938) = 755090 / 7
LCM(805,938) = 107870
