Question

Copy and complete the factor tree. Then write the prime factorization of the number.

Short answer

Prime factorization of the number 180 is $180=3\times 3\times 5\times 2\times 2$.

Step-by-step solution

Step-1-Find the missing numbers in the tree

Consider, the factor tree as,

$\begin{array}{l}180=9\times 20\\ 9=3\times 3\\ 20=5\times 4\\ 4=2\times 2\end{array}$

Step-2- Complete the tree

The complete factor tree is,

Step-3- Complete the tree

Prime factorization of the number 180 is $180=3\times 3\times 5\times 2\times 2$.
