What is the largest prime of 18 and 24?
largest prime factor of 18 & 24 = 3factors of :18= 1, 3, 6, 9, 1824= 1, 2, 3,4, 6, 8, 12, 24,prime factors of 18 & 24 = 2, 3largest prime factor of 18 & 24 = 3
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 are the common factors of 5 and 18?
Since 5 is prime, and not a factor of 18, the only positive integer common factor of 5 and 18 is 1.
How would you use prime factorization for 1 over 18 minus 1 over 30?
Prime factorisation of 18 = 2*3*3 Prime factorisation of 30 = 2*3*5 Then 1/18 = 5*1/5*18 = 5*90 (using the prime factor of 30 that is not in 18) and 1/30 = 3*1/3*30 = 3*90 (using the extra prime factor of 18 that is not in 30) So 1/18 + 1/30 = 5/90 + 3/90 = 8/90 = 4/45
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 factor and prime numbers for 18?
The factors of 18 are: 1 2 3 6 9 18The prime factors are: 2 3
What is the greatest common factor of 18 and 49?
The GCF of 18 and 49 is 1. These numbers are relatively prime
What is the greatest common factor of 29 9 and 18?
1. 29 is prime therefore it has to be 1.
What is the greatest common factor of 18 and 35?
The factors of 18 are 1, 2, 3, 6, 9, and 18.The factors of 35 are 1, 5, 7, and 35.The only common factor is 1, so the greatest common factor is 1. This means they are relatively prime.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 35 are 5 and 7.There are no common prime factors, therefore they are relatively prime, which means the greatest common factor is 1.18 = 2 x 3 x 3, 35 = 5 x 7. There is no common factor other than 11 - they are relatively primeThe GCF is 1.The GCF is 1.The GCF is 1.
What are the factor and prime factor of 36?
Factors: 1, 2, 3, 4, 6, 9, 12, 18, 36.Prime Factors: 2, 3
What are the common factors of 13 and 18?
The only common factor of 13 and 18 is 1 because they are co-prime.
What is the GCF of 18 28?
Since the number 7 is prime, and is not a factor of 18, the greatest common factor (GCF) of these three numbers is 1.
