Lets's calculate LCM of 470,9002
2 | 470, 9002 |
235, 4501 |
∴ So the LCM of the given numbers is 2 x 235 x 4501 = 2115470
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/2115470
Therefore, the GCF of Fractions 450/470,5781/9002 is 3/2115470
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 470,9002 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(470,9002) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(470,9002) x common factors =2 x 1 = 2
LCM(470,9002) = ( 470 × 9002 ) / 2
LCM(470,9002) = 4230940 / 2
LCM(470,9002) = 2115470
