9) 100,160,120
10) 105,148,100

Answer 1

Dupa descompunerea in factori primi alegem factorii comuni si necomuni la puterea cea mai mare pentru a calcula cmmmc:
1) 2x3=6
2) 2^3 x 3 = 24
3) 36= 3^2 x 2^2 
4) 3^2 x 13 = 9 x 13 = 117
5) 90
6) 20
7) 48
8) 6=2x3; 16=2^4; 54= 2 x 3^3 cmmmc= 2^4 x 3^3 = 16 x 27 = 432 
9) 2^2 x 5^2; 2^5 x 5; 2^3 x 3 x 5  si cmmmc = 2^5 x 3 x 5^2 = 32 x 3 x 25 = 2400
10) 3x7x5; 2^2 x 37, 2^2 x 5^2 si cmmmc= 2^2 x 3 x 5^2 x 7 x 37 = 4x3x25x7x37= 77700

————–
[9;18;12]=2²•3²=36

4)
9=3²
3=3
13=13
———–
[9;3;13]=3²•13=9•13=117

5)
5=5
90=2•3²•5
45=3²•5
—————–
[5;90;45]=2•3²•5=2•9•5=90

6)
2=2
