If two numbers are in the ratio 6 : 13 and their L.C.M. is 312, find the numbers.
Given:
Two numbers are in the ratio 6 : 13 and their L.C.M. is 312.
To do:
We have to find the numbers.
Solution:
Let the numbers be $6x$ and $13x$.
This implies,
LCM of the numbers $6x$ and $13x=6\times13\times x$
$=78x$
Therefore,
$78x=312$
$x=\frac{312}{78}$
$x=4$
$\Rightarrow 6x=6(4)=24$
$\Rightarrow 13x=13(4)=52$
The numbers are $24$ and $52$.
