Question

Identify the mistakes in the following problems and correct them.

HCF of $12,60$ and $40$$=2$

Answer 1

First, we need to do the prime factorization of given numbers.

$$\begin{gathered} 12=2\times 2\times 3 \\ 60=2\times 2\times 3\times 5 \\ 40=2\times 2\times 2\times 5 \end{gathered}$$

Hence, HCF of $12,60$ and $40$$=2\times 2$$=4$

Thus the given statement is false.
