The factors of 12 are:
1, 2, 3, 4, 6, 12
The factors of 18 are:
1, 2, 3, 6, 9, 18
The common factors are:
1, 2, 3, 6
The least of these is 1. There can only be one least. The next smallest is 2.
When their GCF is greater than 1. When they have a prime factor in common.
The least common factor of any set of positive integers is 1.
They must have at least one factor other than 2 and 5.
1. The numbers 55 and 27 are "relatively prime", meaning they have no common factor other than 1.
Assuming the second even number is equal to 4 or greater, than the highest common factor of the two numbers is equal to an even number 2 or greater. Why can't an odd factor be used? Any odd factor must be multiplied by (at least) 2 to create an even product (ie. the 1st even number). That same odd factor must be multiplied by (at least 2) and any other number to create a 2nd even product, thereby making the Greatest Common Factor (at least) 2 times the odd number....which is an even number.
There is no common factor as you have to have at least 2 numbers to have a "common" factor. The greatest factor of 225 other than 225 is 75
If you want the "least", then there can only be one. If there were more than one,then one would be smaller than the other, and they wouldn't both be "least".The least common factor of 12 and 18 is ' 1 '.In fact, the least common factor of any two numbers is ' 1 '.
The least common factor of any set of integers is 1.
The greatest common factor can't be a smaller number than the least common factor, but if you meant least common multiple, 7 and 28 have a GCF of 7 and an LCM of 28.
The least common factor for two numbers is always one. The least common multiple for two numbers which have no common factors greater than one is their product.
When their GCF is greater than 1. When they have a prime factor in common.
The least common factor of any set of integers is 1. The least common multiple can never be smaller than the larger of the two starting numbers.

The least common factor of any set of numbers is 1.By definition, 1 is a factor of all numbers. And you cannot have a factor that is less than one so it is the least.In this case 1, is also the greatest common factor since the numbers have no other common factors. We call these numbers relatively prime.
They have no common factor other than 1.
None. The least common factor is defined only for two or more numbers: one number cannot have a LCF. In any case, the least factor of any number is 1. So 91 cannot be a least common factor of any number since 1 is a factor and 1 is less than 91.
I think you mean least common multiple. It would be 315.There are no factors of 35 and 9 other than 1.
