The HCF is the largest number that both numbers can be divided by. If the HCF is 1, that would suggest that the two numbers share no prime factors. Thus, any two numbers which are coprime will have an HCF of 1. Consecutive numbers are good examples here - 15 and 16, 27 and 28, 104 and 105, all have an HCF of 1.

HCF of 100?
You need at least two numbers to find a GCF.
What is hcf of 9 and 11?
HCF is the highest common factor of two or more numbers. As they 9 and 11 are co-primes hence HCF is 1.
What is the HCF of 680?
To have a HCF, you need at least 2 numbers. There is no HCF in just 1 number.
When the HCF of two numbers is 1 what they are called?
Relatively prime or co-prime.
What is the greatest common factor of two consecutive numbers?
The GCF of two consecutive numbers is always 1. The GCF of any set of numbers can't be greater than the smallest of the differences between the numbers.
What numbers have an HCF of 1?
An HCF is the product of any common prime factors of two numbers. If two numbers have no common prime factors, then the HCF will be 1. For example, 10 and 21. The prime factors are 2x5 and 3x7. There is nothing in common, and so the HCF of 10 and 21 is 1. Two consecutive numbers will always have the HCF of 1.
What is HCF of two consequtive numbers?
It is: 1
What will be the HCF of two consecutive numbers?
It will be 1
What is the HCF of two prime numbers?
1
Hcf of two consecutive numbers?
Will be 1
What is the hcf of two concecutive odd numbers?
It is: 1
What is the HCF of two co prime numbers?
The answer is always 1.
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 consecutive odd numbers?
The GCF of consecutive odd numbers is 1.
HCF of 100?
You need at least two numbers to find a GCF.
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 hcf of 9 and 11?
HCF is the highest common factor of two or more numbers. As they 9 and 11 are co-primes hence HCF is 1.
