Lets's calculate LCM of 240,4269
3 | 240, 4269 |
80, 1423 |
∴ So the LCM of the given numbers is 3 x 80 x 1423 = 341520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/341520
Therefore, the GCF of Fractions 3280/240,8790/4269 is 10/341520
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 240,4269 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(240,4269) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(240,4269) x common factors =3 x 1 = 3
LCM(240,4269) = ( 240 × 4269 ) / 3
LCM(240,4269) = 1024560 / 3
LCM(240,4269) = 341520
