Greatest Common Factor
We found the factors 400,4020 . The biggest common factor number is the GCF number.
So the greatest common factor 400,4020 is 20.
Lets's calculate LCM of 866,732
2 | 866, 732 |
433, 366 |
∴ So the LCM of the given numbers is 2 x 433 x 366 = 316956
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/316956
Therefore, the GCF of Fractions 400/866,4020/732 is 20/316956
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 866,732 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(866,732) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(866,732) x common factors =2 x 1 = 2
LCM(866,732) = ( 866 × 732 ) / 2
LCM(866,732) = 633912 / 2
LCM(866,732) = 316956
