Question

Write the prime factorization of the number 70

Short answer

The prime factorization is$2\times 5\times 7$ .

Step-by-step solution

Step -1 - Apply the concept of   Prime Factorization

In this, simply use the concept of Prime factorization of the numbers in such a way that a number is divided by the smallest prime number from start and then divide again and again and try to make them as short as possible.

Step -2 – Find the Factorization

Here, the numbers are70 .

Divide the above number by the prime numbers that is $2,3,5,7,\mathrm{...}$according to the numbers.

Then,

$\begin{array}{l}70÷2=35\\ 35÷5=7\\ 7÷7=1\end{array}$

Step -3 – Finding the Prime factor

Now, from the above factorization, the prime Factors of70 will be

$2\times 5\times 7$.
