When is the LCM of two numbers neither of the numbers?
When their GCF is greater than 1. When they have a prime factor in common.
What is the least common factor of 17 and 7?
The least common factor of any set of positive integers is 1.
What is the rule for the denominator of recuring decimals?
They must have at least one factor other than 2 and 5.
What is the greatest common factor of 55 and 27?
1. The numbers 55 and 27 are "relatively prime", meaning they have no common factor other than 1.
Is the greatest common factor of two even numbers always even?
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.
What is the greatest common factor of 225 other than 225?
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
What is the least common factor of 12 and 18?
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 '.
What is the least common factor of 5 and 7?
The least common factor of any set of integers is 1.
What are two numbers that have a Greatest Common Factor of 7 and a Least Common Factor of 28?
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.
When is the LCM of two numbers neither of the numbers?
When their GCF is greater than 1. When they have a prime factor in common.
What is the least common factor for two numbers if there are no common factors greater than 1?
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.
Can the least common factor ever be smaller than the two starting number?
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.
What is the least common factor of 8 12 21?
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.
What is the least common factor greater than 50?
51
What is the greatest common factor of 3 and 175?
They have no common factor other than 1.
What number has an least common factor of 91?
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.
What is one number that is a least common factor of 32?
I must say, this is a mess.-- If you want the least something, then you only get one of them. If there were two leasts,then you would immediately ask which least is less than the other least.-- "Common" means "same for both". There's nothing 'common' about just one thing,and just one number has no 'common' factors.-- The least common factor of any group of two or more numbers is always ' 1 '.
