七个自然数怎样的和等于它们的积

排列结果太多了，我假设这7个数字分别是a,b,c,d,e,f,g
我用程序做的，我假设1-8之间的数字
<%
for a=1 to 8
for b=1 to 8
for c=1 to 8
for d=1 to 8
for e=1 to 8
for f=1 to 8
for g=1 to 8
if (a+b+c+d+e+f+g=a*b*c*d*e*f*g) then
Response.Write "a=" & a &"<br>"
Response.Write "b=" & b &"<br>"
Response.Write "c=" & c &"<br>"
Response.Write "d=" & d &"<br>"
Response.Write "e=" & e &"<br>"
Response.Write "f=" & f &"<br>"
Response.Write "g=" & g &"<br>--------------------<br>"
end if
next
next
next
next
next
next
next
Response.Write "Over"
%>
运行结果：
a=1
