I must personally admit that trying to comprehend this monstrous statement is equilivant to swallowing an American bullfrog.<\/p>\n\n\n\n<p class=\"has-pale-ocean-gradient-background has-background\">You are given any positive integer N. Without loss of generality, assume it is 12.<\/p>\n\n\n\n<p class=\"has-white-color has-midnight-gradient-background has-text-color has-background has-link-color wp-elements-af44d8447e2ca358b9445190651be7d5\">How many odd factors does 12 have? They are 1 and 3. So 12 has 2 odd factors.<\/p>\n\n\n\n<p class=\"has-blush-light-purple-gradient-background has-background\">Recall that this equals to &#8220;the total number of ways to express N as the sum of one or more consecutive positive integers.&#8221; So, the total number of ways to express n as {the sum of consecutive positive integers} is 2.<\/p>\n\n\n\n<p class=\"has-very-light-gray-to-cyan-bluish-gray-gradient-background has-background\">For example, we can express 12 as 3 + 4 + 5. This is indeed a sum of consecutive positive integers. 12 is also equal to 12 (Recall that 12 is also a sum of one or more consecutive positive integers.) There aren&#8217;t any more ways (see for yourself!)<\/p>\n\n\n\n<p class=\"has-white-color has-cool-to-warm-spectrum-gradient-background has-text-color has-background has-link-color wp-elements-133056790a3e7942259ea25d2c8cddc0\">So yes, it is true that given a positive integer N, its total number of odd factors equals the number of ways to write N as the sum of one or more consecutive positive integers.<\/p>\n\n\n\n<p class=\"has-pale-pink-background-color has-background\">One more example:<\/p>\n\n\n\n<p class=\"has-pale-pink-color has-midnight-gradient-background has-text-color has-background has-link-color wp-elements-7e77e6bbe5dfbd34a446d366a07ee411\">14. 14 has 2 odd factors, 1 and 7. We can write 2 + 3 + 4 + 5 and just 14 by itself. This equals two ways so yes, the Consecutive Integer Partition Theorem (for these two cases, at least) is true!<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Don&#8217;t Forget! <\/strong><em>When finding factors of N, don&#8217;t forget that 1 also qualifies as an odd number. <\/em><\/p>\n\n\n\n<p><strong>Also Don&#8217;t Forget! <\/strong><em>When finding ways to express N as a sum of some numbers, don&#8217;t forget that N itself is also a way.
