3 <p>The GCF is the largest number that can divide two or more numbers without leaving any remainder. GCF is used to share items equally, to group or arrange items, and to schedule events. In this topic, we will learn about the GCF of 96 and 40.</p>

4 <h2>What is the GCF of 96 and 40?</h2>

5 <p>The<a>greatest common factor</a><a>of</a>96 and 40 is 8. The largest<a>divisor</a>of two or more<a>numbers</a>is called the GCF of the number.</p>

6 <p>If two numbers are co-prime, they have no common factors other than 1, so their GCF is 1. The GCF of two numbers cannot be negative because divisors are always positive.</p>

7 <h2>How to find the GCF of 96 and 40?</h2>

8 <p>To find the GCF of 96 and 40, a few methods are described below </p>

24 <p>Find the GCF of 96 and 40 using the<a>division</a>method or Euclidean Algorithm Method. Follow these steps:</p>

26 <p><strong>Step 1:</strong>First, divide the larger number by the smaller number Here, divide 96 by 40 96 ÷ 40 = 2 (<a>quotient</a>), The<a>remainder</a>is calculated as 96 - (40×2) = 16 The remainder is 16, not zero, so continue the process</p>

25 <p><strong>Step 1:</strong>First, divide the larger number by the smaller number Here, divide 96 by 40 96 ÷ 40 = 2 (<a>quotient</a>), The<a>remainder</a>is calculated as 96 - (40×2) = 16 The remainder is 16, not zero, so continue the process</p>

27 <p><strong>Step 2:</strong>Now divide the previous divisor (40) by the previous remainder (16) Divide 40 by 16 40 ÷ 16 = 2 (quotient), remainder = 40 - (16×2) = 8</p>

26 <p><strong>Step 2:</strong>Now divide the previous divisor (40) by the previous remainder (16) Divide 40 by 16 40 ÷ 16 = 2 (quotient), remainder = 40 - (16×2) = 8</p>

28 <p><strong>Step 3:</strong>Now divide the previous divisor (16) by the previous remainder (8) Divide 16 by 8 16 ÷ 8 = 2 (quotient), remainder = 16 - (8×2) = 0 The remainder is zero, the divisor will become the GCF. The GCF of 96 and 40 is 8.</p>

27 <p><strong>Step 3:</strong>Now divide the previous divisor (16) by the previous remainder (8) Divide 16 by 8 16 ÷ 8 = 2 (quotient), remainder = 16 - (8×2) = 0 The remainder is zero, the divisor will become the GCF. The GCF of 96 and 40 is 8.</p>
