Question

The expression $21m-49n$ factored using the GCF is

Answer 1

Step-by-step explanation:

• Factors of 9 = 1,3,9
• Factors of 9 = 1,3,9Factors of 21 = 1,3,7,21
• Factors of 9 = 1,3,9Factors of 21 = 1,3,7,21
• Factors of 9 = 1,3,9Factors of 21 = 1,3,7,21 What's the largest common factor? 3.
• Factors of 9 = 1,3,9Factors of 21 = 1,3,7,21 What's the largest common factor? 3.
• Factors of 9 = 1,3,9Factors of 21 = 1,3,7,21 What's the largest common factor? 3. 9/3 = 3
• Factors of 9 = 1,3,9Factors of 21 = 1,3,7,21 What's the largest common factor? 3. 9/3 = 321/3 = 7
• Factors of 9 = 1,3,9Factors of 21 = 1,3,7,21 What's the largest common factor? 3. 9/3 = 321/3 = 7
• Factors of 9 = 1,3,9Factors of 21 = 1,3,7,21 What's the largest common factor? 3. 9/3 = 321/3 = 7 9 + 21 = 3(3 + 7)
