The correct Answer is:
To find the common factors of the given pairs of numbers, we will follow these steps: ### Step 1: Find the factors of 120 To find the factors of 120, we can divide it by numbers starting from 1 up to 120 and check which numbers divide it evenly. - 120 ÷ 1 = 120 - 120 ÷ 2 = 60 - 120 ÷ 3 = 40 - 120 ÷ 4 = 30 - 120 ÷ 5 = 24 - 120 ÷ 6 = 20 - 120 ÷ 8 = 15 - 120 ÷ 10 = 12 So, the factors of 120 are: **1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120.** ### Step 2: Find the factors of 160 Now, let's find the factors of 160 in a similar way. - 160 ÷ 1 = 160 - 160 ÷ 2 = 80 - 160 ÷ 4 = 40 - 160 ÷ 5 = 32 - 160 ÷ 8 = 20 - 160 ÷ 10 = 16 So, the factors of 160 are: **1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160.** ### Step 3: Identify the common factors of 120 and 160 Now, we will compare the factors of both numbers to find the common factors. - Factors of 120: **1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120** - Factors of 160: **1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160** **Common factors are: 1, 2, 4, 5, 8, 10, 20, 40.** ### Step 4: Find the factors of 52 Next, we will find the factors of 52. - 52 ÷ 1 = 52 - 52 ÷ 2 = 26 - 52 ÷ 4 = 13 So, the factors of 52 are: **1, 2, 4, 13, 26, 52.** ### Step 5: Find the factors of 32 Now, let's find the factors of 32. - 32 ÷ 1 = 32 - 32 ÷ 2 = 16 - 32 ÷ 4 = 8 So, the factors of 32 are: **1, 2, 4, 8, 16, 32.** ### Step 6: Identify the common factors of 52 and 32 Now, we will compare the factors of both numbers to find the common factors. - Factors of 52: **1, 2, 4, 13, 26, 52** - Factors of 32: **1, 2, 4, 8, 16, 32** **Common factors are: 1, 2, 4.** ### Final Answers: (a) The common factors of 120 and 160 are: **1, 2, 4, 5, 8, 10, 20, 40.** (b) The common factors of 52 and 32 are: **1, 2, 4.** ---

To find the common factors of the given pairs of numbers, we will follow these steps: ### Step 1: Find the factors of 120 To find the factors of 120, we can divide it by numbers starting from 1 up to 120 and check which numbers divide it evenly. - 120 ÷ 1 = 120 - 120 ÷ 2 = 60 - 120 ÷ 3 = 40 ...
