Answer 1

By applying the lowest common multiple approach, Kyra may have acquired up to 12 rocks.

What does common factor mean?

A common factor is a whole number that is a factor of at least two other numbers. The highest common factor is the largest factor that will divide into two or more numbers (HCF). The phrase "lowest common multiple" refers to the smallest multiple that two or more numbers have in common (LCM).

The least common multiple of 2, 3, and 4 can be used to determine how much rock Kyra has.

Several of:

2 = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20

3 = 3, 6, 9, 12, 15, 18, 21

4 = 4, 8, 12, 16, 20

The smallest number that 2, 3, and 4 have in common is 12. There are therefore 12 rock piles in Kyra's possession.
