What is the least common factor for two numbers if there are no common factors greater 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.
How Can a set of numbers have a GCF greater than 1?
Ex: 30 and 42 The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30 The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42 The common factors are: 1, 2, 3, 6 The Greatest Common Factor: GCF = 6
What numbers greater than 100 have three factors?
Numbers having exactly three factors are the squares of prime numbers. Examples of these numbers greater than 100 are 121, 169, 289, 361, 529, 841, etc.
Are prime numbers rectangular?
No. To be rectangular a number must have two factors greater than 1. If it has two factors greater than 1, it cannot be prime.
When two mixed numbers are greater than 1 are mulitiplied the product will always be?
The product will be greater than 1, when each of the two factors are greater than 1.
Why is greater common factors greater than common factors?
In any list of distinct numbers, one will be greater than the others. In the list of common factors, one will be the greatest.
What is the least common factor for two numbers if there are no common factors greater 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.
What are 2 numbers that have the LCM of no common factors that are greater than one?
Two numbers that have no common factors greater than one are considered co-prime or relatively prime. Their LCM is their product.
What is the LCM of 2 numbers that have no common factors greater than 1?
Their product.
What two numbers have no common factors greater than one?
They are called co-primes.
How do you know when two pairs of numbers will have an LCM that is less than the product of the numbers?
When their GCF is greater than 1. When they have prime factors in common.
Two prime numbers greater than 2 have 2 as a common factor?
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.
How can you determine if the least common multiple of 2 numbers is the product of the 2 numbers or less than the product of the 2 numbers?
If the GCF of a given pair of numbers is 1, the LCM will be equal to their product. If the GCF is greater than 1, the LCM will be less than their product. Or, stated another way, if the two numbers have no common prime factors, their LCM will be their product.
What are two numbers that have no common factors greater than 1?
Such numbers, like 4 and 9, are called relatively prime or co-prime.
How Can a set of numbers have a GCF greater than 1?
Ex: 30 and 42 The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30 The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42 The common factors are: 1, 2, 3, 6 The Greatest Common Factor: GCF = 6
What are the greater common factor of18 and 36?
The Greatest Common Factor depends upon the numbers for which there are common factors and it is the greatest one of them; it can be greater than 18, for example the greatest common factor of 40 and 100 is 20. The greatest common factor must be one of the factors of each of the numbers. As the factors of each number cannot be greater than that number, the greatest common factor of a set of numbers cannot be greater than the least number. If this number is not greater than 18 then the greatest common factor of the numbers cannot be greater than 18. Even if the least number is greater than 18 it is possible that the greatest common factor of a set of numbers is still not greater than 18, for example the greatest common factor of 20, 30 and 50 is 10.
When you multiply 2 positive numbers will the number be equal to or greater than both numbers?
Answer: It will be greater than both the numbers. Answer: It may be greater, equal, or less than the numbers. Examples: 2 x 3 = 6 (greater than both factors) 0.5 x 0.4 = 0.2 (smaller than both factors)
