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 '.)
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 each group of numbers 39 52 91?
The GCF is 13.
What is a common factor-?
A common factor is a factor that is common to 2 or more numbers.Examples:Common factors of 4 and 6 are: 1 and 2Common factors of 15 and 25 are: 1 and 5Common factors of 16 and 24 are: 1, 2, 4, and 8.Common factors of 28 and 42 are: 1, 2, 7 and 14.A common factor is a number that will divide two or more other numbers without leaving a remainder. For example, 3 is a common factor of 3, 6, and 21.List the factors of two numbers. Any number that appears on both lists is a common factor.All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. 2 is a common factor of 4 and 6.All non-zero numbers have factors. Some numbers have the same factors as other numbers. They are said to have those numbers "in common," which was shortened to common factors.
what is the largest factor that two numbers share is called?
The greatest common factor (GCF) of two (or more) numbers is the greatest factor that divides two numbers. To find the GCF you must work out and list the prime factors of each of the numbers. You will see that the numbers have prime factors in common. Multiply those factors the numbers have in common together and this gives you the GCF for the numbers. eg Number A = 18, Prime factors = 2*3*3 Number B = 24, Prime factors = 2*2*2*3 The Prime factors that A and B have in common are 2 and 3 Multiply them together = 6 6= the GCF of 18 and 24
