Question

7) The students in a class can be divided into groups of 2, 3, 5, and 6. What is the
least number of children this class can have? [2]
Your answer​

Answer 1

Answer:

30

Step-by-step explanation:

As it's given the class can be divided into groups of 2,3,5 and 6.

So we have to find LCM(Least Common Factor) of 2,3,5 and6 .

LCM of 2,3,5 and 6=

|2,3,5,6

2|1, 3,5,3

3|1, 1,5, 1

5|1, 1, 1, 1

So the common factors are 2,3 and 5.

Hence, the least number of children the class can have = 2×3×5=30.
