Lets's calculate LCM of 660,640
2 | 660, 640 |
2 | 330, 320 |
5 | 165, 160 |
33, 32 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 33 x 32 = 21120
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 704/21120
Therefore, the GCF of Fractions 704/660,2112/640 is 704/21120
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 660,640 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(660,640) = 20
common factors(in case of two or more numbers have common factors) = 1
GCF(660,640) x common factors =20 x 1 = 20
LCM(660,640) = ( 660 × 640 ) / 20
LCM(660,640) = 422400 / 20
LCM(660,640) = 21120
