1 and 12, 2 and 6, 3 and 4
The factors of 12 are: 1, 2, 3, 4, 6, 12. Those which are not multiples of 3 are: 1, 2, 4.
2 x 6 = 12 2 and 12 are factors of 12 2 and 6 are a factor pair of 12
A factor is a number which, when multiplied by another number, produces a given number.... 5 is a factor of 20A common factor is a number which is a factor of two or more given numbers.... 2 is a common factor of 20 and 60.The greatest common factor is the largest number which is common to two or more given numbers - so while 2 and 3 and 5 are the factors of 30, and 2 and 3 and 7 are the factors of 42..... the greatest common factor of 30 and 42 is 6 (which is 2 x 3).The GCF can be no larger than the smallest number given in the problem. If no other numbers is a common factor, then the GCF will be the number 1. For example: Find the GCF of 12, 20, and 36. The smallest number in the problem is 12. The factors of 12 are 1, 2, 3, 4, 6, and 12. 12 is the largest factor, but it does not divide evenly into 20. Neither does 6, but 4 will divide into both 20 and 36 evenly. Therefore 4 is the GCF. Find the GCF of 12 and 13. Factors of 12 are 1, 2, 3, 4, 6, and 12. 12 is the largest factor, but it does not divide evenly into 13. neither does 6, 4, 3, and 2. Therefore the only factor common to both 12 and 13 is the number 1, the GCF.
The factor that does not belong in the sequence is 1. The sequence follows a pattern of multiplying by 2: 2 x 2 = 4, 4 x 2 = 8, 8 x 2 = 16. However, 1 does not fit this pattern and disrupts the sequence.
4 is not a factor of 18 and is a factor of both 8 and 12
1 and 3
1, 2 1, 2, 3, 4, 6, 12
The least common factor of any pair of numbers, including 10 and 12, is 1. The factors of 10 are 1, 2, 5, and 10. The factors of 12 are 1, 2, 3, 4, 6, and 12. The common factors of 10 and 12 are 1 and 2. Therefore, the least common factor (the smallest common factor) is 1.
Since 12 is a factor of 72, all of its factors are common.
The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 16 are 1, 2, 4, 8, and 16. The common factors of 12 and 16 are 1, 2, and 4. Therefore, the least common factor (the smallest common factor) is 1.
Everything except 1, 2, 61 and 122
12 is not a factor of any number between 1 and 10. But 1, 2, 3, 4, and 6 are factors of 12 .
They are: 1 2 3 4 6 and 12
