Lets's calculate LCM of 29,45,45
3 | 29, 45, 45 |
3 | 29, 15, 15 |
5 | 29, 5, 5 |
29, 1, 1 |
∴ So the LCM of the given numbers is 3 x 3 x 5 x 29 x 1 x 1 = 1305
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/1305
Therefore, the GCF of Fractions 84/29,40/45,572/45 is 4/1305
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 29,45,45 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(29,45,45) = 1
common factors(in case of two or more numbers have common factors) = 45
GCF(29,45,45) x common factors =1 x 45 = 45
LCM(29,45,45) = ( 29 × 45 × 45 ) / 45
LCM(29,45,45) = 58725 / 45
LCM(29,45,45) = 1305
