Prime factorization involves rewriting numbers as products
The HCF and the LCM of 1848, 132 and 462 are 66 and 1848 respectively
<h3>How to determine the HCF</h3>The numbers are given as: 1848, 132 and 462
Using prime factorization, the numbers can be rewritten as:
The HCF is the product of the highest factors
So, the HCF is:
In (a), we have:
So, the LCM is:
Hence, the HCF and the LCM of 1848, 132 and 462 are 66 and 1848 respectively

Since the problem is not telling us the height of Silvio, we are going to assume it is not relevant for our calculations.
Let
the altitude of the incoming plane. We know for our problem that the distance between Silvio and the tower is 3 miles, Also we know that the angle of elevation to the plane is 40°. With this information we can create a triangle as shown in the figure. We need a function that relates the angle of elevation with its opposite and adjacent sides, that function is tangent.
We can conclude that we should use the trig function tangent to model this situation; also, we can conclude that the equation that describes this situation is.
