Lowest common multiple of 4 and 10

LCM of 4 and 10 is 20

Step-by-step explanation:

TO Find the LCM or Least Common Multiple we have to factor the numbers into smallest possible values bu using prime Numbers

(prime Numbers are 2,3,5,7, ...)

factorization of numbers are

4 = 2 * 2

10 = 2 * 5

Now

Common factor between 4 and 10 is 2

Common factor will be written once because it is common in between both so

LCM = 2 * 2 * 5

(one two was common in both and on two was only in factor of 4 and not in 10)

so

multiplying gives

LCM = 20

Answer: 20

Step-by-step explanation:

2^2=4

5*2=10

2^2 and 5 would be multiplied
