The prime factors of 80 are 2 and 5. For them to be common, they need to be compared to another set of prime factors.
No. each number has more factors than just 1 and 64 or 1 and 80
This one is a little tough to decipher. The prime factorization of 80 is 24 x 5, which means that the prime factors of 80 are 2 and 5. For them to be common, they need to be compared to another set of prime factors.
The common factors are: 1, 2, 4, 8, 16.
The factors of 64 are:1, 2, 4, 8, 16, 32, 64The factors of 80 are:1, 2, 4, 5, 8, 10, 16, 20, 40, 80The common factors are:1, 2, 4, 8, 16
To find the greatest common factor (GCF) of 64, 80, and 96, we must first find the prime factorization of each number. 64 = 2^6, 80 = 2^4 * 5, and 96 = 2^5 * 3. The GCF is the product of the common prime factors raised to the lowest power they appear in any of the numbers, which in this case is 2^4 = 16. Therefore, the GCF of 64, 80, and 96 is 16.
80 and 189 are relatively prime as they have no common factors other than 1.
1, 2, 4, 8 and 16
2 and 5
1, 2, 4, 8, 16
The greatest common factor of 32 and 80 is 16. The common factors of 32 and 80 are 1, 2, 4, 8, and 16. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 32 are 1, 2, 4, 8, 16, and 32. The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. 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 32 are 2, 2, 2, 2, and 2. The prime factors of 80 are 2, 2, 2, 2, and 5. 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.
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.
