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.
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 common factor of 16 and 20?
Ah, what a happy little question we have here! The common factor of 16 and 20 is 4. You see, a common factor is a number that can divide into both 16 and 20 without leaving a remainder. Just like how we blend colors on our palette, finding common factors is a gentle way of seeing the connections between numbers.
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 are the prime common factors of 16?
16 has only one prime factor: 2
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.
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.
What are the factors and prime factors of 16?
16 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 5 factors of 16 are 1, 2, 4, 8, and 16.Note: It has an odd number of factors because 16 is a square number (4 x 4).The factor pairs of 16 are 1 x 16, 2 x 8, and 4 x 4.The proper factors of 16 are 1, 2, 4, and 8 or,if the definition you are using excludes 1, they are 2, 4, and 8.The prime factors of 16 are 2, 2, 2, and 2. Note: There is repetition of these factors, so if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed.The only distinct prime factor (listing each prime factor only once) of 16 is 2.The prime factorization of 16 is 2 x 2 x 2 x 2 or, in index form (in other words, exponential form), 24.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
What is the greatest common factor of 16 and 81?
The greatest common factor (GCF) of 16 and 81 is 1. This is because the factors of 16 are 1, 2, 4, 8, and 16, while the factors of 81 are 1, 3, 9, 27, and 81. The only factor that they have in common is 1, making it the greatest common factor.
What is the greatest common factor of 16 and 38 and 72?
The factors of 16 are 1, 2, 4, 8, and 16. The factors of 38 are 1, 2, 19, and 38. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The factors common to all three are 1 and 2. Therefore, the greatest common factor is 2. The greatest common factor can also be determined from the prime factors. The prime factors of 16 are 2, 2, 2, and 2. The prime factors of 38 are 2 and 19. The prime factors of 72 are 2, 2, 2, 3, and 3. The prime factors they have in common are a single 2, so 2 is the greatest common factor.
