补充资料：亲密数

如果a的因子和等于b，b的因子和等于a，且a〈〉b，则称a，b为亲密数对。

如编程找出10000以内的亲密数来:

option explicit

dim i as long, j as long, x as long

private sub form_load()

me.show

for i = 1 to 10000

doevents

x = yzh(i)

if x <= 10000 and i < x then

if yzh(x) = i then

text1 = text1 & "(" & i & "," & x & ")" & chr(13) & chr(10)

yzhout (i)

yzhout (x)

end if

end if

next

text1 = text1 & "计算完成"

end sub

private function yzh(n as long) as long

yzh = 0

for j = 1 to n / 2

if n mod j = 0 then yzh = yzh + j

next

end function

private function yzhout(n as long) as long

dim yzh as long

text1 = text1 & n & "=1"

yzh = 1

for j = 2 to n / 2

if n mod j = 0 then

text1 = text1 & "+" & j

yzh = yzh + j

end if

next

text1 = text1 & "=" & yzh & chr(13) & chr(10)

end function

程序计算结果，有5组亲密数对，程序输出是：

(220,284)

220=1+2+4+5+10+11+20+22+44+55+110=284

284=1+2+4+71+142=220

(1184,1210)

1184=1+2+4+8+16+32+37+74+148+296+592=1210

1210=1+2+5+10+11+22+55+110+121+242+605=1184

(2620,2924)

2620=1+2+4+5+10+20+131+262+524+655+1310=2924

2924=1+2+4+17+34+43+68+86+172+731+1462=2620

(5020,5564)

5020=1+2+4+5+10+20+251+502+1004+1255+2510=5564

5564=1+2+4+13+26+52+107+214+428+1391+2782=5020

(6232,6368)

6232=1+2+4+8+19+38+41+76+82+152+164+328+779+1558+3116=6368

6368=1+2+4+8+16+32+199+398+796+1592+3184=6232

计算完成.
