What is the least number having 100 as a factor?
And by the way, if 100 is a factor, that also means that the number must be divisible by 100.
A common factor of 100 and 25 is 25. 25 goes into both 100 and 25. A good way to check other numbers is divide the larger number by the smaller number. If you have 10 and 25, that won't work, so you will have to find numbers that go into both. An easy way to do this is find different ways to get each number. Example: 2x5=10 5x5=25 5 goes into each number at…
The least common factor is a term often mistakenly given to either the greatest common factor (GCF) or the least common multiple (LCM). This term is not often used because it does not describe a useful relationship between numbers. Since 1 evenly divides all integers, 1 is technically the least common factor for any set of integers. The smallest non-one common factor of 50 and 100 is 2.
All the numbers up to 100 are factors in some numbers up to 100. For example, 1 is a factor of every number and 2 is a factor of all the even numbers. The numbers greater than 50 are only factors of themselves among the numbers up to 100, 95 is only a factor of itself, because the next number for which it is a factor is 190, which is greater than 100.
