If the HCF (Highest Common Factor) of two numbers is 1, then the two numbers are relatively prime and their LCM is the product of the two numbers.
12, 24, 120
It's never. A factor divides into a number without remainder, so the biggest it can be is the number itself.
No. The GCF of any two numbers is also a factor of their difference. The difference between consecutive numbers is 1 so their GCF must also be a factor of 1. The only factor of 1 is 1 - and hence the result.
Those are called prime numbers.
No, the GCF of two numbers can never be greater than the smaller number.
No, the greatest common factor is never greater than the smallest number. The greatest common factor is the largest integer that divides evenly into all of the numbers listed.
When the numbers have a common factor (other than 1).
The least common factor for two numbers is always one. The least common multiple for two numbers which have no common factors greater than one is their product.
No, the greatest common factor cannot be larger than any of the numbers in the set.
Yes it is.
When they have a common prime factor. When their GCF is greater than 1.
No.
No prime number greater than 2 has 2 as a factor. A prime number has only two factors, 1 and the number itself. All prime numbers have 1 as a common factor. Numbers with any number besides 1 as common factors are composite numbers.
No, a factor cannot be larger than the numbers it is compared to.
When their GCF is greater than 1. When they have a prime factor in common.
No, it's never greater than the smallest number.
