l.m.c:
最小公倍數
e.g.4&6的最小公倍數
4*1=4, 4*2=8,4*3=12
6*1=6, 6*2=12
4&6的最小公倍數 is 12
h.c.f最大公因數
e.g.4&6的最大公因數
4的因數:1,2,4
6的因數:1,2,3,6
最大的是2
so 4&6的最大公因數 is 2

It should be LCM and HCF.
LCM = Lowest Common Multiple.
LCM is to work out the smallest multiple that can be divided to become a few numbers.
[e.g.] 28, 36. LCM = 252.
HCF = Highest Common Factor.
HCF is to work out the highest factor that can be multiplied to become a few numbers.
[e.g.] 28, 36. HCF = 4.
Hope I can help you!

L.C.M係最小公倍數,H.C.F係最大公因數.
e.g.24同12的最小公倍數係24.
12=12,24,36,48,60.............
24=24,48,72,96,120..............
e.g.6同9的最大公因數係3.
e.g.24同12的最小公倍數係24.
12=12,24,36,48,60.............
24=24,48,72,96,120..............
e.g.6同9的最大公因數係3.

應該係L.C.M同H.C.F,
L.C.M係最小公倍數,
例如6(6=2x3)同8(8=2x2x2)既L.C.M就係24(24=2x2x2x3),
H.C.F係最大公因數,
例如36(36=2x2x3x3)同24(24=2x2x2x3)既H.C.F就係12(12=2x2x3)
L.C.M係最小公倍數,
例如6(6=2x3)同8(8=2x2x2)既L.C.M就係24(24=2x2x2x3),
H.C.F係最大公因數,
例如36(36=2x2x3x3)同24(24=2x2x2x3)既H.C.F就係12(12=2x2x3)
