Is there a common prime factor of 16 and 25?
There are no common prime factors!
Are the numbers 9 and 16 relatively prime?
Yes, 9 and 16 are relatively prime. They do not have any prime factors in common.
What is the common factor of 16 and 20?
The factors of 16 are 1, 2, 4, 8, and 16. The factors of 20 are 1, 2, 4, 5, 10, and 20. The largest of the factors they have in common is 4, so 4 is the greatest common factor. Using prime factorization: The prime factors of 16 are 2, 2, 2, and 2. The prime factors of 20 are 2, 2, and 5. The prime factors in common are 2 and 2, so the greatest common factor is 2 x 2 = 4.
How do you know if a fraction is in its simplest form in your head?
If it has no prime factors in common. The prime factors of 16 are all twos and the prime factors of 27 are all threes. 16/27 has to be in simplest form.
What is the greatest common factor of 16 and 81?
The GCF of 16 and 81 is 1. 16's prime factors are 2, 2, 2 and 2 81's prime factors are 3, 3, 3 and 3 Therefore, they do not have any common prime factors, and so the greatest common factor is 1.
What is the greatest common factor of 16 and 80?
I know that 16 x 5 = 80, so the greatest common factor of 16 and 80 must be 16, since the greatest common factor cannot be larger than the small number. But, if you did not know this, you would need to compare their factors. The factors of 16 are 1, 2, 4, 8, and 16. The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The largest of the factors they have in common is 16, so 16 is the greatest common factor. Or, you can determine the greatest common factor by their prime factors. The prime factors of 16 are 2, 2, 2, and 2. The prime factors of 80 are 2, 2, 2, 2, and 5. The prime factors they have in common are four 2s, so 2 x 2 x 2 x 2 = 16 is the greatest common factor.
What is the process for getting the GCF of 16 and 20?
The factors of 16 are:1, 2, 4, 8, 16The factors of 20 are:1, 2, 4, 5, 10, 20The common factors are:1, 2, 4The Greatest Common Factor:GCF = 4
What is the common factor between 48and 16?
The factors of 48 are 1,2,3,4,6,8,12,16,24, and 48. The factors of 16 are 1,2,4,8, and 16. The common factors of 16 and 48 are 1,2,4,8, and 16.
What is the greatest common factor of 16 and 63?
Since 16 is 24, its only factors other than 1 are multiples of 2, which means that because 63 is not an even number, the greatest common factor is 1. Another way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 16 are 1, 2, 4, 8, and 16. The factors of 63 are 1, 3, 7, 9, 21, and 63. The only common factor is 1. Therefore, the greatest common factor is 1. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 16 are 2, 2, 2, and 2. The prime factors of 63 are 3, 3, and 7. There are no prime factors in common, which means the numbers are relatively prime, so the greatest common factor is 1.
What are the prime common factors of 16?
16 has only one prime factor: 2
What is the greatest common factor of 16 and 64?
The GCF of 16 and 64 is 16.The easiest way to determine the greatest common factor is if you notice that 16 is a factor of 64, which means that 16 is the greatest common factor.One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 16 are 1, 2, 4, 8, and 16.The factors of 64 are 1, 2, 4, 8, 16, 32, and 64.The common factors are 1, 2, 4, 8, and 16. Therefore, the greatest common factor is 16.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 16 are 2, 2, 2, and 2.The prime factors of 64 are 2, 2, 2, 2, 2, and 2.The prime factors in common are 2, 2, 2, and 2, so the greatest common factor is 2 x 2 x 2 x 2 = 16.The GCF is 16.The GCF of 64 and 16 is 16.
Are 16 and 27 relatively prime?
Yes. The factors of 16 are 1,2,4,8,16 and the factors of 27 are 1,3,9,27 making 1 their only common factor. This makes them relatively prime.
