Divisibility by Primes

Divisibility tests by primes such as 7, 13, 17 and 19 are not generally discussed in the school curriculum. However, in Vedic Mathematics (also known by the name “High Speed Mathematics”; see Box 1), techniques for testing divisibility by such primes are discussed, but without giving any proofs. In this article, proofs of these techniques are discussed.
