So the greatest common factor 38,721,171 is 1.
Lets's calculate LCM of 26,73,828
2 | 26, 73, 828 |
13, 73, 414 |
∴ So the LCM of the given numbers is 2 x 13 x 73 x 414 = 785772
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/785772
Therefore, the GCF of Fractions 38/26,721/73,171/828 is 1/785772
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 26,73,828 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(26,73,828) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(26,73,828) x common factors =1 x 2 = 2
LCM(26,73,828) = ( 26 × 73 × 828 ) / 2
LCM(26,73,828) = 1571544 / 2
LCM(26,73,828) = 785772
