<p><strong>Step 2:</strong>Now divide the previous divisor (54) by the previous remainder (45) Divide 54 by 45 54 ÷ 45 = 1 (quotient), remainder = 54 - (45×1) = 9</p>
31
<p><strong>Step 3:</strong>Divide again until the remainder is zero Divide 45 by 9 45 ÷ 9 = 5 (quotient), remainder = 45 - (9×5) = 0 The remainder is zero, the divisor will become the GCF</p>
