Answer 1

LCM of 5, 10, 15, and 20 is 60.

Explanation:-

Given:

Find LCM of the 5,10, 15, 20.

LCM of 5 ,10, 15, 20 :-

$\begin{array}{r | l} 5 & 5, 10, 15, 20 \\ \cline{2-2} 2 & 1, 2, 3, 4 \\ \cline{2-2} 2 & 1, 1, 3, 2 \\ \cline{2-2} 3 & 1, 1, 3, 1 \\ \cline{2-2} & 1, 1, 1, 1 \end{array}$

5 x 2 x 2 x 3 = 60.

Hence, LCM of 5, 10, 15 and 20 is 60

Answer 2

Answer:

The LCM of 5 ,10, 15, 20 is 60.

Step-by-step explanation:

The given numbers are

5 ,10, 15, 20

The factors of each number are

$5=1\times 5$

$10=2\times 5$

$15=3\times 5$

$5=2\times 2\times 5$

Multiply all factors except the repleted factors, to find the LCM.The LCM of given numbers is

$LCM=2\times 2\times 3\times 5=60$

Therefore LCM of  5 ,10, 15, 20 is 60.
