Question

any no. multiple by 7,11,13












​

Answer 1

Step-by-step explanation:

Testing divisibility by 7, 11, and 13

The original number is divisible by 7 (or 11 or 13) if this alternating sum is divisible by 7 (or 11 or 13 respectively). The alternating sum in our example is 963, which is clearly 9*107, and not divisible by 7, 11, or 13. Therefore 11,037,989 is not divisible by 7, 11, or 13.
