So the greatest common factor 252,669 is 3.
Lets's calculate LCM of 406,378
2 | 406, 378 |
7 | 203, 189 |
29, 27 |
∴ So the LCM of the given numbers is 2 x 7 x 29 x 27 = 10962
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/10962
Therefore, the GCF of Fractions 252/406,669/378 is 3/10962
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 406,378 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(406,378) = 14
common factors(in case of two or more numbers have common factors) = 1
GCF(406,378) x common factors =14 x 1 = 14
LCM(406,378) = ( 406 × 378 ) / 14
LCM(406,378) = 153468 / 14
LCM(406,378) = 10962
