List the factors for the following numbers. \( \begin{array}{ll}\text { a. } 72 & \text { b. } 49\end{array} \)

It seems that I cannot directly factor the numbers 72 and 49 using the tool. However, I can provide the factors manually. ### a. Factors of 72 To find the factors of 72, we can list all the pairs of numbers that multiply to give 72: 1. \(1 \times 72\) 2. \(2 \times 36\) 3. \(3 \times 24\) 4. \(4 \times 18\) 5. \(6 \times 12\) 6. \(8 \times 9\) Thus, the complete list of factors of 72 is: \[ 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72 \] ### b. Factors of 49 For 49, we can do the same: 1. \(1 \times 49\) 2. \(7 \times 7\) Thus, the complete list of factors of 49 is: \[ 1, 7, 49 \] ### Summary - Factors of 72: \( 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72 \) - Factors of 49: \( 1, 7, 49 \)
