2 x 3 x 5 = 30
It can. Square numbers have repeated factors.
There isn't one. Negative numbers have prime factors and numbers don't stop. The smallest positive numbers with a prime factor is 2.
Square numbers have repeated factors. 6 x 6 = 36
The smallest possible number to get from 3 and 4 as your factors is 12...

There is no such number. Since there are infinitely many prime numbers, the only number that can be divided by all of them is zero. But that can also be divided by numbers with repeated factors.
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. The smallest of these is known as the least common factor. Since 1 is a common factor of every set of integers, the least common factor of any set of integers is 1.
The repeated factor of 102 is 10.
18 has square factors, but no repeated ones.
Gcf you use when you are finding the greatest factor for the numbers. Lcm you use when you are finding the smallest multiple in the numbers factors
All nonzero numbers have factors. Some numbers have some of the same factors as other numbers. These are common factors. All nonzero numbers have 1 as a factor. The least common factor of any set of positive integers is 1.
