Answer:
20
Explanation:
you can get a composite number not just by multiplying 1 times the number itself
but other numbers too
4 is composite because its made by multiplying 1 and 4 & 2 and 2
NOT 3 because there are only 2 numbers that can make three : 1 & 3
composite numbers have more than two positive divisors :
not just 1 times the number itself
smallest two-digit composite number = 10 &
smallest composite number = 4
prime factorization of 10 = 2 ⋅ 5
prime factorization of 4 = 2 ⋅ 2
LCM of 10 & 4 = 2 ⋅ 2 ⋅ 5 = 20
smallest two-digit composite number = 10
smallest composite number = 4
least common multiple = 20
