What is the least common multiple of 70 and 100?

Answer 1

To find the LCM of 10,40, and 100, lets list the first several multiples of these numbers:

Multiples of 10: 10,20,30,40,50,60,70,80,90,100

Multiples of 40: 40,80,120,160,200,240,280,320,360,400

Multiples of 100: 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000

We see that there is the multiple 200 shared between 40 and 100. We know that 200 is a multiple of 10, too, because 10 x 20= 200, so the lowest common multiple of 10, 40, and 100 is 200.

Answer 2

The least common multiple of 10 and 100 is 100 because if you write down all the multiples of 10 and write down all the multiples of 100 the only number that you see that the number 10 and the number 100 have in common is 100.

Answer 3

You need at least two numbers to find an LCM.

Answer 4

100. 10 goes into 100 10 times and 100 goes into 100 1 time.

Answer 5

The LCM is: 300

Answer 6

The LCM of 32 and 100 is 800 (3^2 * 2^5).

Answer 7
