1 and 3
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors because they are factors that the numbers have in common. 3 is a factor of 12. 3 is a factor of 15. 3 is a common factor of 12 and 15.
12 and 24
Because all of 12's multiples are even numbers, 12 doesn't divide evenly into 16839. Therefore, 12 is not a factor of 16839.
Multiple. Factors go into numbers, numbers go into multiples.
No odd whole numbers have 12 as a factor. 1 and 3 are odd numbers that are factors of 12.
All numbers with 12 as a factor have 2 as a factor, but not all have 10 as a factor.
It is for numbers that are multiples of 12, but not for other numbers.
4,6,8,10,12,14,16,18,20,22,24,26
Multiples of 12, like 12, 24 and 36.
The greatest common factor of the numbers 12 and 42 is 6.
Since 6 is a factor of 12, it is automatically the GCF.
2 is a common factor of 12 and 24 because it can evenly divide both numbers without any remainder. This is because 12 is equal to 2 multiplied by 6, and 24 is equal to 2 multiplied by 12. Since 2 is a factor of both 12 and 24, it is considered a common factor of the two numbers.
Factors cannot be larger than the numbers they are compared to. 4 is a factor of 12. 12 is a multiple of 4.
1 and 3
The highest common factor of the numbers 12 and 21 is 3.
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors because they are factors that the numbers have in common. 3 is a factor of 12. 3 is a factor of 15. 3 is a common factor of 12 and 15.
