Why would 2 be the greatest common factor in a problem?
Because the numbers being asked about are consecutive even numbers.
What does it mean to share a common factor?
A common factor of several numbers is a number that can divide evenly into each one of them. '10' is a common factor of 20 and 30. '5' is a common factor of 10 and 15. '3' is a common factor of 6, 9, and 12. '2' is a common factor of all even numbers. '1' is a common factor of all whole numbers.
What is the greatest common factor of 73 and 127?
This is tricky. Once you determine that 73 is a prime number then you can ignore 127 (since 73 is not a factor of 127). So, the greatest common factor is 1. Note: if you asked 73 and 146 then the answer would be 73. Anytime one of the numbers is a prime - then the answer is EITHER 1 or the prime number (if the other number is a multiple of the prime).
Why wouldn't you be asked to find the greatest common multiple?
It doesn't exist. There is no multiple so great that it can't be multiplied further. The greatest common multiple of any set of integers is infinite.
What is the least common factor of 11 and 7?
Both 7 and 11 are prime numbers. Each one has no other factors besides '1' and itself.So the only factor they have in common is ' 1'.(Even if you had picked 2 numbers with 100 factors in each one, you asked for the "least"common factor. Regardless of what the numbers may be, that's always ' 1 '.)
