Use factors and multiples to organize temperature and rainfall records.

Organize the Records

Use common factors to organize records without leftovers. GCF means greatest common factor.

A weather station has 54 temperature records and 72 rainfall records to file. Find the GCF of the two record counts.

GCF of 54 and 72 =
