Answer 1

Answer:

of 50,60,70

Step-by-step explanation:

the number of 50 will go to decimal and of 60 will also go to decimal and 70 too

Answer 2

AnsWer :

2100.

Solution :

Prime factorization, Number 50.

$\begin{array}{r | l} 2 & 50 \\ \cline{2-2} 5 & 25 \\ \cline{2-2} 5 & 5 \\ \cline{2-2} & 1 \end{array}$

Prime factorization, Number 60.

$\begin{array}{r | l} 2 & 60 \\ \cline{2-2} 2 & 30 \\ \cline{2-2} 3 & 15 \\ \cline{2-2} 5 & 5 \\ \cline{2-2} 5 & 1 \end{array}$

Prime factorization, Number 70.

$\begin{array}{r | l} 2 & 50 \\ \cline{2-2} 5 & 25 \\ \cline{2-2} 5 & 5 \\ \cline{2-2} & 1 \end{array}$

$\rule{200}1$

We can express,

$\tt50\dashrightarrow 2 \times 5 \times 5.$

$\tt60\dashrightarrow2 \times 5 \times 3 \times 2.$

$\tt70\dashrightarrow2 \times 5 \times 7.$

Then, LCM ( 50, 60 and 70 ) = 2100.

Therefore, the LCM of given number be 2100.
