Answer:
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
