2個數最大公因數是15,最小公倍數是75.求這2個數.

2個數最大公因數是15,最小公倍數是75.求這2個數.

15=3*5
75=3*5*5
這兩個數都含有3和5這兩個因數,所以兩個數中一個數還含有5.
即3*5*1=15
和3*5*5=75
15和75
最大公因數是(較小數)15;最小公倍數是(較大數)75。
因為15和75呈倍數關係。
15和75
對75進行因式分解得到75=5*5*3
因為必須有因式15,固得到這個數只有2種可能是5*3或者5*5*3
即15和75
15和75
15和75

有2個數,它們的最小公倍數是60,最大公因數是5,求這2個數.
60÷5=12
12=3×4=1×12
所以,一個數是:5*3=15,另一個是:5*4=20
或者說:一個數是:5*1=5,另一個數是:5*12=60
