Solved examples: finding factors of a number (grade 6 math problems)

📚 Quick Study Guide

• 🔢 A factor is a number that divides evenly into another number.
• ➗ To find the factors of a number, think: What numbers can I divide the number by without a remainder?
• 💡 Start with 1 and the number itself, as they are always factors.
• 📝 Then, check numbers in order (2, 3, 4, etc.) to see if they divide evenly.
• 🧮 If a number divides evenly, it's a factor!
• 📌 Factors always come in pairs. For example, if 2 is a factor, there's another number that, when multiplied by 2, gives you the original number.
• 🧐 Keep going until you find all the pairs.
