A piece of rope can be cut into an exact number of 6 m lengths.
Gnesinka [82]

Answer:

24 m

Step-by-step explanation:

the smallest common multiple of 6 and 8.

I know already what that is (24) based on experience, but let's do this formally via prime factoring :

6 ÷ 2 = 3

3 ÷ 2 no

3 ÷ 3 = 1 finished

8 ÷ 2 = 4

4 ÷ 2 = 2

2 ÷ 2 = 1 finished

6 = 2 × 3

8 = 2 × 2 × 2

the smallest common multiple is the combination of the longest streaks per prime factor.

and that is 3 times a 2 and 1 time a 3 :

2 × 2 × 2 × 3 = 24 m
