Juanita wants to give bags of stickers to her friends. She wants to give the same number of stickers to each friend. She's not sure if she needs 4 bags or 6 bags of stickers.How many stickers could she buy so there are no stickers left over? explain

Answer:

To find the number of stickers, you need to find the LCM of the number of bags.

Number of bags are either 4 or 6.
4 = 2*2 = 2²
6 = 2*3
So LCM = 2² * 3 = 12

So she could to buy 12 stickers. So if she needs 4 bags, she will put 3 stickers in each of them and  if she needs 6 bags, she will put 2 stickers in each of them and there would be no stickers left.
