Question

Find the common factors of $56$ and $120$.

Answer 1

Determine the common factor:

If a number divides two or more numbers evely. then such a number is called a common factor of the numbers.

The factors of the given numbers $56$ and $120$. are,

$$\begin{gathered} 56:1,2,4,7,8,14,28,56. \\ 120:1,2,3,4,5,6,8,10,12,15,20,24,30,40,60,120. \end{gathered}$$

On observing these factors, we can conclude that,

Common factors are$\begin{array}{l}1,2,4,8\end{array}$

Hence the common factors of $56$ and $120$. are $1,2,4,$ and $8$.
