| ## Description
 | ||
| <section id="description">只能被素数2和3整除的最大整数≤100是96,因为96 = 32 * 3 = 25 * 3。对于两个不同的素数p和q,令M(p,q,N)是最大的正整数≤N,只能被p和q整除,并且如果不存在这样的正整数,则M(p,q,N)= 0。 <p>例如M(2,3,100)= 96。 M(3,5,100)= 75而不是90因为90可以被2,3和5整除。另外M(2,73,100)= 0因为不存在可以被2和73整除的正整数≤100。 </p><p>设S(N)为所有不同M(p,q,N)的和。 S(100)= 2262。 </p><p>找到S(10 000 000)。 </p></section>
