Q. Find all the factor pairs for

45

and complete the equations.

\newline

45 = \_\_\_ \times 45

\newline

45 = 3 \times \_\_\_

\newline

45 = 5 \times \_\_\_

Identify Factors: Identify the first factor pair by using the number itself and $1$ . $\newline$ Calculation: $45 = 1 \times 45$
Find Next Pair: Find the next factor pair by checking divisibility starting from the smallest prime number. $\newline$ Calculation: $45 \div 3 = 15$ , so $45 = 3 \times 15$
Continue Finding Pairs: Continue finding factor pairs by checking divisibility by the next smallest prime number. $\newline$ Calculation: $45 \div 5 = 9$ , so $45 = 5 \times 9$
