Question

Write the prime factors of $28\mathrm{and}36$ through the division method.

Answer 1

Prime factors by using the division method.

The prime factors of $28$ through the division method are computed as,

$\therefore 28=2\times 2\times 7$

Thus, the prime factors of $28$ are $2$ and $7$.

The prime factors of $36$ through the division method are computed as,

$\therefore 36=2\times 2\times 3\times 3$

Thus, the prime factors of $36$ are $2$ and $3$.

Hence,

The prime factors of $28$ are $2$ and $7$.

The prime factors of $36$ are $2$ and $3$.
