What is the least common multiple of 4 and 12?<br> 4<br> 12<br> 24<br> 48
Nostrana [21]

Answer: 12

Step-by-step explanation: To find the least common multiple or lcm of 4 and 12, begin by listing the first few multiples of each number.

<em><u>Multiples of 6</u></em>

1 × 6 = 6

2 × 6 = 12

3 × 6 = 18

Notice that we skipped 0 × 6 in our list of multiples.

That's because 0 × 6 is 0 and our least common multiple can't be 0.

When listing the multiples of 12, it's a good idea to keep an eye on the list of multiples for 4 so that we will notice when we find a least common multiple.

<em><u>Multiples of 12</u></em>

1 × 12 = 12

Notice that 12 is also a multiple of 6 so our least common multiple is 12.

We can stop here because all other multiples

that we find will be greater than 12.

So the least common multiple or LCM of 4 and 12 is 12.

storchak [24]
150 + 15x = 400
(-150) 150 + 15x = 400 (-150)
15x = 250
(/15) 15x = 250 (/15)
x = 16.67
So Chia can invite 16 people
