We want to find the greatest common factor (GCF) of the terms in the given expression. To do so, we will consider coefficients and variables separately.
16 t- 40 y
Let's start by finding the GCF of 16 and 40.
Factors of16:& 1,2,4, 8,and16
Factors of40:& 1,2,4,5, 8,10,20,and 40
We found that the GCF of the coefficients is 8. To find the GCF of the variables, we need to identify the variables repeated in both terms, and write them with their minimum exponents.
\begin{aligned}
\textbf{Factors of }\bm{1^\text{st}}\textbf{ Variable:}&\ t\\
\textbf{Factors of }\bm{2^\text{nd}}\textbf{ Variable:}&\ y
\end{aligned}
We see that there are not any repeated variable factors.
Thus, the GCF of the expression is 8. Now we can write the given expression in terms of the GCF.
16t-40y ⇔ 8* 2t- 8* 5y
Finally, we will factor out the GCF.
8* 2t- 8* 5y ⇔ 8(2t-5y)
