What is the greatest common factor of 17 and 18 and 20?
Since 17 is a prime number, the greatest common factor of 17, 18, and 20 is 1.
What is the greatest common factor of 18 19 and 20?
It is 1 because 19 is a prime number
What is the greatest common factor of 15 9 and 18?
The GCF of 9, 15, and 18 is 3. The prime factorization of 9 is 3*3. The prime factorization of 15 is 3*5 The prime factorization of 18 is 2*3*3 So the greatest common factor is 3.
What is the greatest common factor of 7 and 18?
The GCF of 7 and 18 is 1 because 7 is a prime number and seven does not go into 18.
What is the greatest common factor of 18 and 75?
The greatest Common Factor (GCF) of 18 and 75 is 3.
What is the greatest common factor of 5 and 18?
Answer: 1 Since 5 is a prime number, the only possible common factors are 1 and 5. Because 18 is not divisible by 5, the only common factor, and thus the greatest common factor, is 1.
What is the greatest common factor of 18 and 73?
The GCF of a prime number and a composite number is 1 if the former is not a factor of the latter. 73 is a prime number and 18 is a composite number and 73 is not a factor of 18 because 18 is not divisible by 73. So, GCF(73, 18) = 1.
What ls the greatest common factoer of 19 and 18?
um well i believe it is 1, because 19 is a prime number.
What is the Greatest Common Factor of 29 and 18?
The GCF is 1. The number 29 is prime, so there are no common factors other than 1.
What is the greatest common factor of 18 and 51?
The greatest common factor of 18 and 51 is 3.18 ÷ 3 = 651 ÷ 3 = 17Method: One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 18 are 1, 2, 3, 6, 9, and 18.The factors of 51 are 1, 3, 17, and 51.The common factors are 1 and 3. Therefore, the greatest common factor is 3.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 18 are 2, 3, and 3.The prime factors of 51 are 3 and 17.The prime factors in common are a single 3, so the greatest common factor is 3.The greatest common factor of 51 and 18 is 3
what is the largest factor that two numbers share is called?
The greatest common factor (GCF) of two (or more) numbers is the greatest factor that divides two numbers. To find the GCF you must work out and list the prime factors of each of the numbers. You will see that the numbers have prime factors in common. Multiply those factors the numbers have in common together and this gives you the GCF for the numbers. eg Number A = 18, Prime factors = 2*3*3 Number B = 24, Prime factors = 2*2*2*3 The Prime factors that A and B have in common are 2 and 3 Multiply them together = 6 6= the GCF of 18 and 24
What are the greatest common factor of 13 and 18?
13 is prime, so it's greatest common factor with anything is either 1 (if the other number isn't a multiple of 13) or 13 (if it is).
