The answer will depends on what the factor puzzle is!
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.
the least common multiple is what the numbers you are using divide into. e.g. 3 and 6 have 12 as the common factor. the greatest common factor is what divides into your numbers. 6 and 9 have 3 as the greatest common factor
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.
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.
