Question

What are the prime factors of $57$?

Answer 1

Find out the prime factors:

A method of breaking a number into its prime numbers such that forming the number when multiplied is defined as Prime factorization

Divide 57 by the least prime number by which it is completely divisible $\mathrm{i}.\mathrm{e}.3$

$\frac{57}{3}=19$

Again divide by the least prime number by which it is completely divisible $\mathrm{i}.\mathrm{e}.19$.

$\frac{19}{19}=1$

Now we get the quotient is equal to$1$.

$\therefore 57=3\times 19$

Hence, the prime factor of $57$ is $57=3\times 19$
