24 has 8 as a factor.
The difference is between factor pairs and distinct factors. With square numbers, one of the factor pairs will be the same number twice. When listing the distinct factors, that number is only listed once.
There are no factors of 50 in that range.
5, 10, 15 and 20 have five as a factor. The number 16 has five factors.
30 is the only number between 20 and 50 that is a factor of 60
I think this is one for trial and error. Are you counting 1 as a factor?
The common factors of 22 and 20 are: 1 and 2.
One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 12 are 1, 2, 3, 4, 6, and 12.The factors of 20 are 1, 2, 4, 5, 10, and 20.The factors of 26 are 1, 2, 13, and 26.The common factors are 1 and 2. Therefore, the greatest common factor is 2.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 12 are 2, 2, and 3.The prime factors of 20 are 2, 2, and 5.The prime factors of 26 are 2 and 13.The prime factors in common are a single 2, so the greatest common factor is 2.Another way to approach this is to look at the differences between the numbers. The difference between 12 and 20 is 8. The difference between 20 and 26 is 6. The greatest common factor cannot be greater than the smallest difference between the numbers, and must be a factor of the differences between the numbers. So, the greatest common factor of 6 and 8 will also be the greatest common factor of 12, 20, and 26. Next, you can compare the difference of the differences: the difference between 6 and 8 is 2, which divides both 6 and 8, so the greatest common factor of 6 and 8 is 2. Thus, the greatest common factor of 12, 20, and 26 is 2.2126,23,2,22010,25,2,2262,13The only common factor is 2, the GCF.
The factors of 50 are: 1, 2, 5, 10, 25, 50 None of them is between 11 and 20.
20
The GCF of 18, 20, and 32 is 2. Factors of 18... 1,2,3,6,9 & 18 Factors of 20... 1,2,4,5,10 & 20 Factors of 32... 1,2,4,8,16 & 32... Therefore the GCF would be 2 !
The GCF of 9 and 20 is 1. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 9 are 1, 3, and 9. The factors of 20 are 1, 2, 4, 5, 10, and 20. The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 9 are 3 and 3. The prime factors of 20 are 2, 2, and 5. There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1. Another way to approach this is to look at the difference between 9 and 20, which is 11. The greatest common factor of two numbers cannot be larger than the difference between the two numbers and must be a factor of the difference. Since 11 is a prime number, the greatest common factor must be either 1 or 11. The numbers 9 and 20 are not divisible by 11, so the greatest common factor must be 1.
Since 10 is a factor of 20, all of its factors are common.
