Introduction

When dealing with numbers, one of the fundamental concepts in mathematics is the idea of divisibility. In this context, we are looking for the largest number that can divide both 12 and 32 without leaving a remainder. This concept is crucial in various mathematical operations, including finding the greatest common divisor (GCD) of two numbers.

Understanding Divisibility

To find the largest number that can divide both 12 and 32 without a remainder, we need to understand the concept of divisibility. A number is said to be divisible by another number if the remainder is zero when the first number is divided by the second. In other words, if a number 'a' is divisible by 'b', then 'a' can be expressed as 'b' multiplied by an integer 'c', where 'c' is the quotient.

Factors of 12 and 32

To find the largest number that can divide both 12 and 32 without a remainder, we need to find the factors of both numbers. The factors of a number are the numbers that can divide the given number without leaving a remainder.

Factors of 32

The factors of 32 are: 1, 2, 4, 8, 16, and 32.

Finding the Greatest Common Divisor (GCD)

The GCD of two numbers is the largest number that can divide both numbers without leaving a remainder. To find the GCD, we need to find the common factors of both numbers and then select the largest one.

Common Factors of 12 and 32

The common factors of 12 and 32 are: 1, 2, and 4.

Greatest Common Divisor (GCD)
