Answer:
40
Step-by-step explanation:
Using the method of prime factors
8 = 2 × 2 × 2 = 2³
2 = 2
5 = 5
Then LCM = 2³ × 5 = 8 × 5 = 40
Answer:
40
Step-by-step explanation:
The goal of LCM is to get the least common number that can divide any of the numbers given without turning them into fractions until all of them are divided to 1.
The least number that can divide any of the numbers is 2, dividing through we remain with 8/2=4, 2/2=1, and 5. Notice how the 5 remains the same, since dividing it by 2 will turn it into a fraction
Divide through by 2 again, we get 4/2=2, 1, and 5
Divide through by 2 yet again, we get 2/2=1, 1, and 5
Divide through by 5, we get 1, 1, and 1
The LCM is now multiplications of all the least numbers used above= 2*2*2*5=40
