Step 1
Writing the prime factors of each denominators of the fraction
We have the fraction
\(\displaystyle\frac{{1}}{{2}},\frac{{1}}{{4}},\frac{{1}}{{5}},\frac{{1}}{{8}},\frac{{1}}{{10}},\frac{{1}}{{16}},\frac{{1}}{{20}},\frac{{1}}{{25}}\)
Step 2
Now,
Prime factor of \(\displaystyle{2}={2}\)
Prime factor of \(\displaystyle{4}={2}\cdot{2}\)
Prime factor of \(\displaystyle{5}={5}\)
Prime factor of \(\displaystyle{8}={2}\cdot{2}\cdot{2}\)
Prime factor of \(\displaystyle{10}={2}\cdot{5}\)
Prime factor of \(\displaystyle{16}={2}\cdot{2}\cdot{2}\cdot{2}\)
Prime factor of \(\displaystyle{20}={2}\cdot{2}\cdot{5}\)
Prime factor of \(\displaystyle{25}={5}\cdot{5}\)
