Question

HCF of 85 and 405 by proper

Answer 1

Step 1. Divide the larger number by the smaller one: 
405 ÷ 85 = 4 + 65;

Step 2. Divide the smaller number by the above operation's remainder: 
85 ÷ 65 = 1 + 20;Step 3. Divide the remainder from the step 1 by the remainder from the step 2: 
65 ÷ 20 = 3 + 5;Step 4. Divide the remainder from the step 2 by the remainder from the step 3: 
20 ÷ 5 = 4 + 0;At this step, the remainder is zero, so we stop: 
5 is the number we were looking for, the last remainder that is not zero. 
This is the greatest common factor (divisor).

Greatest (highest) common factor (divisor)
