Question

The LCM of 2 and 5 is 10. Find next 5 common multiples

Answer 1

Answer:

Multiples of 2 are: 2, 4681012 14, 16, 18, 20, etc.

Multiples of 5 are: 510152025 etc.

Therefore, common multiples of 2 and 5 = 10, 20, . .etc.

[It can easily be seen that each of the common multiples 10, 20, etc., is exactly divisible by both 2 and 5].

Answer 2

Next 5 common multiples of 2 and 5 are 20,30,40,50, and 60.

xt 5 common multiples of 2 and 5 are 20,30,40,50, and 60. GIVEN

LCM of 2 and 5 = 10

TO FIND

Next 5 common multiples.

SOLUTION

We can simply solve the above problem as follows;

We know that LCM of number is smallest number which is the multiple of both numbers.

It is given;

LCM of 2 and 5 = 10

We know that all the multiples of 2 end in even number (0,2,4,6,8)

And all the multiple of 5 end in 5 or 0.

So, Common multiple of 2 and 5 will be numbers which has zero in the units place.

Hence,The next 5 common multiples of 2 and 5 are 20,30,40,50, and 60.
