The LCM of 10 and 25 is 50. You can find the LCM by dividing the product of a pair of numbers by their GCF: The product of 10 and 25 is 250. The GCF of 10 and 25 is 5. (10 = 2*5 and 25 = 5*5) The LCM of 10 and 25 is 250/5 = 50. You can also list the multiples of each number in the set and identify the lowest one in both lists: Multiples of 10 are 10, 20, 30, 40, 50, and so on. Multiples of 25 are 25, 50, 75, and so on. So the LCM of 10 and 25 is 50.
The first five multiples of 10 are 10,20,30,40,50.... 1 * 10 = 10 2 * 10 = 20 3 * 10 = 30 4 * 10 = 40 5 * 10 = 50
500 contains 50 multiples of 10.
10 ,20 ,30 ,40 ,50
Since 10 is a multiple of 5, all multiples of 10 will also be multiples of 5. Test the theory. 30, 50, 100... All multiples of 10, and also of 5.
There are fifty. 50 x 10 = 500
35 and 70 both have 7 and 5 as prime factors
10
There are three numbers between 10 and 50 which are divisible by both 3 and 5. All numbers that are multiples of 3 and 5 are the multiples of the lowest common multiples (lcm) of 3 and 5 which is 15. The multiples of 15 between 10 and 50 are {15, 30 and 45}, thus there are 3 numbers.
4 and 8 are multiples of 2. 6 and 9 are multiples of 3. 40 and 50 are multiples of 10.

The first 10 multiples of 10 are: 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100.
The first 10 multiples of 10 are: 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100.
