What is the greatest common factor of two or more prime numbers?
The greatest common factor of two or more prime numbers is 1.
What is the GCF of 125 and 200?
25 is the greatest common factor. 5 is the greatest prime factor.
When the greatest common factor of two numbers is 1 then the two numbers are said to be what?
If the greatest common factor is 1, then the numbers are said to be co-prime or relatively prime.
What is the factor tree of negetive 98?
Factor trees lead to prime factorizations. Negative numbers don't have prime factorizations. We'll do 98. If you want, you can put -1 in front of it. 98 49,2 7,7,2
What is the greatest common factor of 51 and 73?
73 is a prime number so 51,3x17 and 73 only have the number 1 as the greatest common factor.
Do you do a factor rainbow for greatest common factor?
You do a factor rainbow to find a prime factorization. You compare prime factorizations to find a greatest common factor.
How can you tell by looking at the prime factorizations of two whole numbers that their greatest common factor is 1?
If they have no prime factors in common, their GCF is 1.
Do factor trees always work for determining the greatest common factors?
If you construct them correctly, factor trees always work to determine the prime factorization of a number. Once you compare the prime factorizations of two or more numbers, it is relatively easy to find the greatest common factor of them from there.
What is the greatest common factor of 410 using prime factorizations?
2 x 2 = 42 x 5 = 10The GCF is 2.
List two methods that can be used to find the greatest common factor of a set of numbers?
Prime factorization and the Euclidean algorithm
What is the greatest common factor of 14 and 35 by using their prime factorizations?
2 x 7 = 14 5 x 7 = 35 The GCF is 7.
Is the greatest common factor of 22 and 64 relatively prime?
2 is the greatest common factor and it is prime
Can the greatest common factor of two numbers be prime?
Yes. The greatest common factor of 4 and 10 is 2, which is a prime number. The greatest common factor of 51 and 81 is 3, which is a prime number.
How do you find the greatest common factor in the hundreds and thousands?
The same as with smaller numbers. Every composite number, no matter the size, can be expressed as the product of prime factors. Comparing prime factorizations will give you the GCF.
What is the greatest prime factor of 40 and 63?
The greatest prime factor of 40 is 5. The greatest prime factor of 63 is 7. They do not have any prime factors in common.
What is the greatest common factor of 51 and 20?
Greatest common factor of 20 & 51 is 1. Factors of 20 are 1, 2, 4, 5, 10 & 20. Factors of 51 are 1, 3, 17 & 51. The only common factor is 1, so GCF is 1. Alternate method: Prime factorization of 20 = 2x2x5 Prime factorization of 51 = 3x17 From the prime factorizations it is clear that 1 is the GCF of 20 and 51.
Which pair of numbers has a greatest common factor that is a prime number 54 and 99 or 80 and 114?
The greatest common factor of 54 and 99 is 9, which is not prime. The greatest common factor of 80 and 114 is 2, which is prime.
