<h3>1.What is the easy trick to find the divisibility of 7 ?</h3>
61
<p>To find the divisibility of 7 we remove the last digit of the number, now<a>square</a>it, and then subtract it from the number left. If the number is zero or a multiple of 7.</p>

<h3>2.Is 7 11 13 divisible?</h3>
63
<p>Multiply 7 × 11 × 13 we get 1001 and if we take any three-digit number we get a six-digit number where the 3-digit number repeats. So the original number will be divisible by 1001 or 7,11 and 13. </p>
