Answer:
The GCF of 45 and 60 is 15.
Step-by-step explanation:
First let us find the factors of 45 and 60.
[tex]\left[\begin{array}{ccc}&45&\\15&*&3\\5*3&&\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}&60&\\15&*&4\\5*3&&2*2\end{array}\right][/tex]
Based on this, you can tell that they both have the number 3 and the number 15 in their factors.
15 > 3
The GCF of 45 and 60 is 15.
