Find the least common multiple of 3 and 7

Mathematics

Sav [38]3 years ago

The LCM of two prime numbers is generally just their product, since they share no common factors.


3 and 7 are both prime numbers, so their LCM (least common multiple) is simply the numbers multiplied together. In this case, the LCM is thus 21.

Answer: 21

Step-by-step explanation: To find the least common multiple or <em>lcm</em> of 3 and 7, begin by finding the first few multiples of each number and comparing the lists.

<u><em>Multiples of 3</em></u>

1 × 3 = 3

2 × 3 = 6

3 × 3 = 9

4 × 3 = 12

5 × 3 = 15

6 × 3 = 18

7 × 3 = 21

<em><u>Multiples of 7</u></em>

1 × 7 = 7

2 × 7 = 14

3 × 7 = 21

Since 21 appears in both lists, we can stop here.

Therefore, the least common multiple of 3 and 7 is 21.

How do you find the area of a triangle ?
katovenus [111]

Answer:

to find the Area of a Triangle, you have to multiply the base times the height of the triangle to find the Area.

Step-by-step explanation:

For example..

If the Base ( bottom part of the triangle) was 10 and the height ( the vertical line of the triangle) was 5, you would multiply them together to get 50. So 5o would be the area of the Triangle.

Ben has 50 drinks and paid 2$ for each. What is 67% of the final price ?
Debora [2.8K]

67% of final price is $67.

Step-by-step explanation:

Given,

Number of drinks Ben has = 50

Amount paid for each drink = $2

Amount paid for 50 drinks = 50*2

Amount paid for 50 drinks = final price = $100

67% of final price = \frac{67}{100}*100

67% of final price = \frac{6700}{100}

67% of final price = $67

67% of final price is $67.
