Answer 2

Given:

Groups which the engineer wants to arrange the carpenters = $4,5,6$

To find:

The least number of carpenters that an engineer must hire

Method used:

LCM of those groups

Step-by-step explanation:

• The number of carpenters required can be identified by taking LCM.
• This is because the number of carpenters required should be a factor of the groups to be arranged.

The LCM factors of $4,5,6$ are $2,2,3,5$

⇒ $2\times2\times3\times5\;=\;60$

The least common multiple of $4,5,6$  is $60$

Answer:

Therefore, the least number of carpenters that an engineer must hire if he wants to arrange them in groups of $4,5,6$ with no carpenter left are $60$.
