Question

What number do you get when you multiply the distinct prime factors of $56$?

• A. $48$
• B. $7$
• C. $14$
• D. $28$
• E. $56$

Answer 1

The correct option is C $14$

You should use a factor tree to determine all the prime factors of $56$, which are $2,2,2$, and $7(56=2\times 2\times 2\times 7)$.

Here, the word distinct means different or unique.

So, the distinct prime factors of $56$ are $2$ and $7$ so that $2\times 7=14$.
