Answer:
The least common multiple would be 20!
Step-by-step explanation:
Now there are different ways of finding out the LCM, but the way I used was Prime Factorization!
List all prime factors for each number.
Prime Factorization of 4 is:
2 x 2 => 22
Prime Factorization of 10 is:
2 x 5 => 21 x 51
For each prime factor, find where it occurs most often as a factor and write it that many times in a new list.
The new superset list is
2, 2, 5
Multiply these factors together to find the LCM.
LCM = 2 x 2 x 5 = 20
In exponential form:
LCM = 2x^{2} * 5x^{1} = 20
LCM = 20
Therefore,
LCM(4, 10) = 20
Hope this helps! :D
