What is a number less than 100 and has factor pairs?
All of the composite numbers less than 100 have factor pairs.
How do you identify prime numbers less than 100?
Numbers can be checked to see if they are primes simply by factoring them. Every prime number has exactly two factors, 1 and the number itself. If there are more or less than 2 factors, the number is not a prime. 1 has only one factor so it is not a prime, and composite numbers have 3 or more factors.
What whole number which is odd less than a hundred has the most factors as the even number?
There are four odd numbers less that 100 that have 6 factor. This does not compare with even numbers that have 12 factors!
What is a prime number factor of 42 less than 10 factor of 70?
2 and 7 are prime numbers less than 10 that are factors of 42 and 70.
Is a prime number a factor of 1?
no, factors of a number would be less than that of the original number. A prime number is a number that has factors of only itself and 1.
Which number is a factor of but not a multiple?
Any factor of the number less than the number itself.
What number less than 13 has the most factors?
1 is the number less than fifty with the fewest number of factors. All other numbers have at least two factors (1, and the integer itself).
Is the greatest common factor of two numbers is equal to the lesser of the number?
Well, not always. The GCF and LCM of 10 and 10 is 10. But apart from that special circumstance, the statement is true. Apart from a number itself, all of its factors are smaller than it. Apart from a number itself, all of its multiples are larger than it. You can't have a GCF that is greater than the smaller number, and you can't have an LCM that is less than the larger one which means that the LCM of two numbers will never be less than the GCF. Factors go into numbers, numbers go into multiples.
How many composite numbers less than 100 will have a factor of 11?
All the multiples of 11 up to 100 except 11 itself which is a prime number
What is a number less than 100 and has factor pairs?
All of the composite numbers less than 100 have factor pairs.
What number is the greatest common factors of a number under 50?
If we are trying to find the two numbers less than 50 with the greatest common factor, we need to pick two numbers with a larger difference between them, since the greatest common factor between two numbers cannot be greatest than the difference between the two numbers. To create a large difference, we will want one number to be close in value to 50. And, for the greatest common factor, we want the other number itself to be the greatest common factor. The greatest common factor that the larger number can have (since it is larger and thus cannot be the greatest common factor itself) is the number which is half its value. So, if we choose the even number closest in value to 50, we get 48. Then, if we take half of it, we get 24. The greatest common factor of 24 and 48 is 24. This is the largest possible greatest common factor of a pair of numbers less than 50.
How do you identify prime numbers less than 100?
Numbers can be checked to see if they are primes simply by factoring them. Every prime number has exactly two factors, 1 and the number itself. If there are more or less than 2 factors, the number is not a prime. 1 has only one factor so it is not a prime, and composite numbers have 3 or more factors.
Why is15 a deficient number?
That means that the sum of the number's factors, less than the number itself, is less than the number in question - in this case, if you add the factors of 15 (except 15 itself, which is also a factor of 15), you get a total that is less than 15.
Factor vrs multiples?
Any number is a factor and a multiple of itself. Other factors are less than the number, other multiples are more. 5 is a factor of 10. 10 is a multiple of 5.
What whole number which is odd less than a hundred has the most factors as the even number?
There are four odd numbers less that 100 that have 6 factor. This does not compare with even numbers that have 12 factors!
What is a prime number factor of 42 less than 10 factor of 70?
2 and 7 are prime numbers less than 10 that are factors of 42 and 70.
Is prime number an abundant number or deficient number?
All prime numbers are going to be deficient, because remember that a prime number's only factors are one and itself. To find if its deficient or abundant, you'd add up all of its factors, excluding itself. If its only other factor beside itself is one, that's obviously less than the number, and therefore it will be deficient.
