Which term describes a number that divides two or more given numbers?

• A. Least Common Multiple
• B. Common Factor
• C. Difference
• D. Minuend

Answer: (B)

A common factor is a number that divides two or more numbers evenly. For example, 12 and 18 share factors 1, 2, 3, and 6, so these are common factors. The term describes any number that divides all given numbers, not just the largest one. This is different from the least common multiple, which is a number that multiple of each given number (a shared multiple), not a divisor. The terms difference and minuend come from subtraction, so they don’t describe numbers that divide others.
