2 is a factor of 4, and 4 is a factor of 4. One (1) is also a factor, but it's not even.
4 and 12 are both even numbers greater than 2. They are composite numbers because 2 is a factor in addition to 1 and itself.
There are square numbers (numbers which are a square of an integer), such as 4. It's factors, listed are 1, 2, and 4. All square numbers have an odd number of factors. Then there's 1, which has only 1 factor: 1. All other numbers have an even number of factors. Prime numbers will have only 2 factors (2 is even).
There is an infinite number of numbers which are not factors of 124. They are all numbers apart from 1, 2, 4, 31, 62, 124.

1, 2 and 4.
2 is a factor of 4, and 4 is a factor of 4. One (1) is also a factor, but it's not even.
The factor numbers are: 4 x 5 2 x 10 1 x 20
1, 2, 4
The word factor means you take a number [in this case it is 2] and you multiply it by another number to reach your desired numbers [in this case your desired numbers are 1, 2, 4, 8 and 16] So ask yourself 2 times what numbers equals 1 or 2 or 4 or 8 or 16 2x 0.5 = 1 2x 1 = 2 2x 2 = 4 2x 4 = 8 2x 8 = 16 Because a number can be multiplied by 2 and get the numbers you said then this 2 can be called a factor of these numbers.
Factor the numbers and then look for the largest factor common to both.Factors of 8 are 1, 2, 4, and 8.Factors of 52 are 1, 2, 4, 13, 26, and 52.The greatest common factor (GCF) is 4.
1, 2, 4, 8
1, 2, 4, 5, 10, 20
No, also 2. All even numbers have at least 1 and 2 in common.
The only number that is a factor of all the numbers from 1 to 100 is the number 1. The only factor of 1 is 1. The factors of 2 are 1 and 2. The factors of 3 are 1 and 3. The factors of 4 are 1, 2, and 4. The factors of 5 are 1 and 5. The factors of 6 are 1, 2, 3, and 6. The factors of 7 are 1 and 7. The factors of 8 are 1, 2, 4, and 8. The factors of 9 are 1, 3, and 9. The factors of 10 are 1, 2, 5, and 10. The only common factor of these ten numbers is 1. Since all numbers are divisible by 1, the greatest common factor is 1.
The lowest common factor of any set of numbers is 1.
To find the GCF of two or more numbers, you can list the factors of each of the numbers and find one that is common to all the numbers.Factors of 2 are 1 and 2Factors of 3 are 1 and 3Factors of 4 are 1, 2, and 4Factors of 8 are 1, 2, 4, and 8Besides 1, the numbers 2, 4, and 8 have 2 as a common factor. They have no factors other than 1 in common with 3.
