The greater number becomes the least common multiple of the 2 numbers.
Ex: 2 and 10. 2 is a factor of 10 and hence 10 is the LCM of 2 and 10
No, the GCF is the lesser of the numbers.
Their product.
No, the lesser.
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.
All numbers with a least common multiple, have that multiple as a factor.
Not with negative numbers. -10 is a multiple of -2.
Yes, the least common multiple of two numbers is always divisible by those numbers' greatest common factor.
When they have a factor in common greater than one.
No, it is not a factor of either of the numbers.
Never.
Use distribution to find the least or greater common factor
There is no answer. There cannot be a lowest common multiple of a single number, such as 30, because "common multiple" means a multiple that two or more numbers have in common. Likewise, there cannot be a highest common factor of a single number, such as 3, because "common factor" means a factor that two or more numbers have in common.
