So the greatest common factor 742,609 is 7.
Lets's calculate LCM of 81,9222
3 | 81, 9222 |
27, 3074 |
∴ So the LCM of the given numbers is 3 x 27 x 3074 = 248994
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/248994
Therefore, the GCF of Fractions 742/81,609/9222 is 7/248994
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 81,9222 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,9222) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(81,9222) x common factors =3 x 1 = 3
LCM(81,9222) = ( 81 × 9222 ) / 3
LCM(81,9222) = 746982 / 3
LCM(81,9222) = 248994
