Question

Sarah's shipping and Ryan's mail services both ship packages.sarah's truck will only carry of 18 packages.if both businesses ended up shipping the same number of package this morning,what is the minimum number of packages each must have shipped LCM or GCF

Answer 1

We will use the Least Common Multiple or LCM. Since we are looking for same number of packages to be shipped.

 

Sarah’s trucks carries 18 while Ryan’s truck only carries 10.

 

Solution:

10 = 10, 20, 30, 40, 80, 90

18 = 18, 36, 54, 72, 90

 

The LCM is 90. Therefore, 90 is the minimum number of packages each must have shipped.
