If the area of a number is defined as the difference between that number's greatest and least prime factors, what is the area of 100 ?
A. 0
B. 2
C. 3
D. 5
E. 9
How to find the area?
OA C
Hi lheiannie07,
Let's take a look at your question.
In the first step we will write as a product of its prime factors.
$$100=2\times2\times5\times5$$
Largest prime factor = 5
Smallest prime factor = 2
As defined in the question statement:
Area = Largest prime factor - smallest prime factor
$$Area=5-2=3$$
Therefore, Option
C is correct.
Hope it helps.
I am available if you'd like any follow up.
