✔ 最佳答案
H.C.F系最小公因數`
L.C.F系最大公因數

咁你要用短除計喎`

我簡你一個簡單方法

H.C.F

6 |_24___
2 |_ 4____
2 |_2_____
1
6x2x2
=12x2
=24
(H.C.F系睇打直數6x2x2)

L.C.F.

6 |_36___
2 |_ 6____
3

6x2x3
=12x3
=36
(L.C.F.睇L字型`咁乘過去)

希望幫到你啦`打得好辛苦嫁`>~<

(24 和 36 的最大公因數(H.C.F.) 是 它們的最小公因數(L.C.F.) 的幾倍?)

24 = 2 x (2 x 2 x 3)

36 = (2 x 2 x 3) x 3

H.C.F. = 2 x 2 x 3 = 12

L.C.F. = 1

12/1 = 12 倍
