What is the gcf if one number is prime and the other is composite?
The answer depends on whether or not the prime number is a factor of the other number.If the prime number is a factor of the other number then the GCF is the prime, otherwise the GCF is 1.
Is the gcf of two numbers are always composite number?
Not necessarily.
Is it true or false that two composite numbers are relatively prime and explain?
Two composite numbers may or may not be relatively prime, depending on their factors. Relatively prime numbers are sets of two or more numbers having 1 as their greatest common factor (gcf). All even numbers have 2 as a common factor, so no even number is relatively prime with any other even number.
What is the gcf of all composite numbers under 100?
The GCF of all the composite numbers under 100 is 1. For e.g 4 & 9 are composite numbers & their GCF is 1, so if we take other composite numbers along with 4 & 9 the GCF will be 1.
What is the GCF of two prime numbers?
A prime number is a number with exactly 2 divisors: 1 and itself. Because of this, the only common divisor of two distinct prime numbers is 1, thus 1 is the gcf. So the correct answer would be: Given two prime numbers, namely x and y, the gcf is --- 1, if x and y are unequally --- x, if x=y.
What is the GCF of 56 and 5?
GCF of a composite number and a prime number is always 1. Here, 5 is a prime number therefore, gcf is 1.
What is the gcf if one number is prime and the other is composite?
The answer depends on whether or not the prime number is a factor of the other number.If the prime number is a factor of the other number then the GCF is the prime, otherwise the GCF is 1.
What is the GCF of 108 and 5?
GCF of a prime number and a composite number is 1 if the composite number is not a multiple of the prime number. Here, 5 is a prime number and 108 is a composite number(not the multiple of 5). Therefore GCF of 108 and 5 is 1.
What is the greatest common factor of 37 and 50?
The greatest common factor of a prime and a composite number is 1 if the composite number is not divisible by the prime number. 37 is a prime number and 50 is a composite number. Also, 50 is not divisible by 37 therefore GCF = 1.
What is the greatest common factor of 72 and 37?
GCF of a prime number and a composite number is 1 if the composite number is a multiple of the prime number. 37 is a prime number and 72 is not a multiple of 37 because it is not divisible by 37. Therefore, GCF of 72 & 37 is 1.
What is the greatest common factor of 47 and 39?
GCF of a prime number and a composite number is 1 if the composite number is not a multiple of the prime number. It is clear here that 39 is not a multiple of 47, therefore GCF(47, 39) = 1.
What is the gcf of 18 and 24 is it prime or composite?
The gcf of 18 and 24 is 6 which is a composite number because it has more than two factors.
Is the gcf of two numbers are always composite number?
Not necessarily.
What is the greatest common factor of 24 and 47?
GCF of a prime number and a composite number is 1 if the prime number is not a factor of the composite number. Here 103 is a prime number and 120 is a composite number. And 120 is not divisible by 103(or 103 is not a factor of 120). So, GCF(103,120) = 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.
Does the greatest common factor have to be a prime number?
No for example the GCF of 24 and 36 is 12 which is a composite number
What happens when you find the the GCF with prime factorization but there is only one number in common?
As long as the other number is not a multiple of the prime number, the GCF will always be 1.
