Find the prime factorization of number 140.

Answer

The prime factorization of 140 is:
$140 = 2 \cdot 2 \cdot 5 \cdot 7$
Which is the same as :
$140 = 2^{2} \cdot 5 \cdot 7$

Explanation

Prime factorization can be nicely visualized by creating a factorization tree.

140 can be written as 10 × 14.	140 10 14
10 can be written as 2 × 5.	140 10 5 2 14
14 can be written as 2 × 7.	140 10 5 2 14 2 7
The end nodes are the prime factors of the number 140.	140 10 5 2 14 2 7
