Find the largest number which can exactly divide 531,783,and 1107

Explanation

To find the largest number that can exactly divide 531, 783, and 1107, we need to calculate the Highest Common Factor (HCF) of these three numbers. Here’s a step-by-step solution:

### Step 1: Prime Factorization of Each Number
First, we will find the prime factorization of each number.

**For 531:**
- Divide by 3: \( 531 \div 3 = 177 \)
- Divide by 3 again: \( 177 \div 3 = 59 \)
