Lets's calculate LCM of 21,753
3 | 21, 753 |
7, 251 |
∴ So the LCM of the given numbers is 3 x 7 x 251 = 5271
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/5271
Therefore, the GCF of Fractions 9405/21,3490/753 is 5/5271
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 21,753 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,753) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(21,753) x common factors =3 x 1 = 3
LCM(21,753) = ( 21 × 753 ) / 3
LCM(21,753) = 15813 / 3
LCM(21,753) = 5271
