Answer :
All three numbers are prime so their lcm is their product.
[tex]LCM(2,7,13)=2\cdot7\cdot13=182[/tex]
[tex]LCM(2,7,13)=2\cdot7\cdot13=182[/tex]
To work out the LCM, we need their prime factors. So:
2 is simple 2 x 1.
7 is also 7 x 1.
13 is also 13 and 1.
They all have in common "1" - so we keep that aside as 1 figure, rather than 3.
We still have the 2, 7 and 13 leftover.
We then multiply the 1 with the other figures.
So 1 x 2 x 7 x 13 is our answer.
Which is = 182.
