Greatest Common Factor
We found the factors 404,921 . The biggest common factor number is the GCF number.
So the greatest common factor 404,921 is 1.
Lets's calculate LCM of 642,982
2 | 642, 982 |
321, 491 |
∴ So the LCM of the given numbers is 2 x 321 x 491 = 315222
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/315222
Therefore, the GCF of Fractions 404/642,921/982 is 1/315222
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 642,982 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(642,982) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(642,982) x common factors =2 x 1 = 2
LCM(642,982) = ( 642 × 982 ) / 2
LCM(642,982) = 630444 / 2
LCM(642,982) = 315222
