What is the HCF of two co-prime numbers is always?
The GCF is always 1.
How would you explain the LCM of the two numbers is their product?
The LCM of two numbers is their product if and only if the two numbers are co prime, that is their HCF is 1. Otherwise their LCM in not their product, in fact, it is their product divided by their HCF.
What is the HCF of 2 co-prime numbers?
The GCF is 1.
Do two or more numbers have to be prime if they are co-prime?
No.
How are 181345913 and 11 relatively prime?
Two numbers are relatively prime (co-prime) if they have no common factor other than 1; that is their highest common factor (hcf) is 1. If one of the numbers is prime, then the two are relatively prime if the prime is not a factor of the other. 11 is a prime. If 11 divides into 181345913, then their hcf is 11 and the two are NOT relatively prime. If 11 does not divide into 181345913 then their hcf is 1 and they are co-prime. A simple test for divisibility by 11: Sum of digits in odd position: 1+1+4+9+3 = 18 Sum of digits in even position: 8+3+5+1 = 17 Difference between the two sums = 18-17 = 1 If this difference is divisible by 11 then so is the original number. The difference is not so 11 is not a factor of 181345913 and the two numbers are relatively prime.
When the HCF of two numbers is 1 what they are called?
Relatively prime or co-prime.
When the hcf of two numbers is 1 it is called what?
The numbers are relatively prime or co-prime.
What is the HCF of two co-prime numbers is always?
The GCF is always 1.
What will be the HCF of two coprime numbers 15 and 37?
The GCF of any two co-prime numbers is 1.
How would you explain the LCM of the two numbers is their product?
The LCM of two numbers is their product if and only if the two numbers are co prime, that is their HCF is 1. Otherwise their LCM in not their product, in fact, it is their product divided by their HCF.
What is the HCF of 2 co-prime numbers?
The GCF is 1.
What is the HCF of 26 and 45?
HCF(26, 45) = 1. The numbers are co-prime.
What is co-prime number?
Numbers are co-prime, or relatively prime, if their GCF is 1. 4 and 9 are relatively prime.
Two consecutive prime numbers which differ by 2 are said to be twin primes while two numbers whose hCF is 1 are called co-primes how many pairs of co-primes are between 1 and 50?
Any number greater than one can be co-prime. I guess the answer is 49.
What is a co-prime factor?
Two numbers are co-prime if they do not have any common factors. The numbers themselves need not be prime.
What is the co-prime numbers?
Two numbers are considered to be co-prime if they share no common prime factors, that is, if their GCF is 1.
Do two or more numbers have to be prime if they are co-prime?
No.
