Question

find the common factors of 15p,20qr,25rp

Answer 1

5 will be the common factor as it can divide all 3 terms

Answer 2

The common factors of 15p, 20qr, 25rp is 5

Step-by-step explanation:

Factors of $15\textrm{p}=3\times5\times \textrm{p}$

factors of $20\textrm{q}\textrm{r}=2\times2\times5\times\textrm {q}\times\textrm{r}$

Factors of $25\textrm{rp}=5\times5\times\textrm{r}\times\textrm{p}$

So common factors of $15\textrm{p}, 20\textrm{qr}, 25\textrm{rp}=5$
