The existence of products of three pairwise coprime integers is investigated in short intervals of the form . A general theorem is proved which shows that such integer products exist provided there is a bound on the product of any two of them. A particular case of relevance to elliptic curve cryptography, where all three integers are of order , is presented as a corollary to this result.
