divisors: 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, and 693. Thus, 693 is tied with <a href="/wiki/315_(number)" class="mw-redirect" title="315 (number)">315</a> for the highest number of divisors for any odd natural number below 900. The smallest positive odd integer with more divisors is 945, which has 16 divisors. Consequently, 945 is also the smallest odd <a href="/wiki/Abundant_number" title="Abundant number">abundant number</a>, having an abundancy index of 1920/945 ≈ 2.03175. </p><p>693 appears as the first three digits after the decimal point in the decimal form for the <a href="/wiki/Natural_logarithm_of_2" title="Natural logarithm of 2">natural logarithm of 2</a>. To 10 digits, this number is 0.<b>693</b>1471805. As a result, if an event has a constant <a href="/wiki/Probability" title="Probability">probability</a> of 0.1% of occurring, 693 is the smallest number of trials that must be performed for there to be at least a 50% chance that the event occurs at least once. More generally, for any probability p, the probability that the event occurs at least once in a sample of n items, assuming the items are independent, is given by the following formula: </p><p>1 − (1 − p)<sup>n</sup> </p><p>For p = 10<sup>−3</sup> = 0.001, plugging in n = 692 gives, to four decimal places, 0.4996, while n = 693 yields 0.5001. </p><p>693 is the <a href="/wiki/Lowest_common_multiple" class="mw-redirect" title="Lowest common multiple">lowest common multiple</a> of 7, 9, and 11. Multiplying 693 by 5 gives 3465, the smallest positive integer divisible by 3, 5, 7, 9, and 11.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>693 is a palindrome in bases 32, 62, 76, 98, 230, and 692.
