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 whole numbers are factors of themselves?
All whole numbers are factors of themselves since a factor is any integer times another integer that equals the number. So, 12 can be factored to 2x6 = 12, 3x4 = 12, and 1x12 = 12. Since 1x12 = 12, 12 and 1 are factors of 12, so 12 is a factor of 12. Since all whole numbers (n) can be written as n*1 = n, all whole numbers are factors of themselves.
What is the probability of selecting an even number out of the whole numbers 1 through 12?
50%, or 1 out of 2. There are 12 numbers, 6 even and 6 odd, so they have equal chance of being odd or even if one is selected
What is a whole number factor?
A factor that is a whole number. The whole number factors of 12 are 1, 2, 3, 4, 6 and 12.
Common factor of 9 and 12?
Take the number 9 and figure out what whole numbers you could multiply together to get that answer. Exclude the numbers and 9. Now take the number 12 and figure out what whole numbers you could multiply to get it. Exclude 1 and 12.When you're all done, look at them to see what number they have in common. That will be your common factor!
How do you find an odd factor of a number?
All nonzero numbers have factors. Some factors are odd numbers. 3 is an odd factor of 12.
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!
How can you express (12 4 16) as a multiple of a sum of whole numbers with no common factor?
It is not possible to express something as a sum of whole numbers with no common factor. All whole numbers have at least 1 as a common factor.
What is an odd number between 520 and 530 with 12 as one of its factor?
An odd number can't have 12 as a factor. 528 does have 12 as a factor.
What whole numbers are factors of themselves?
All whole numbers are factors of themselves since a factor is any integer times another integer that equals the number. So, 12 can be factored to 2x6 = 12, 3x4 = 12, and 1x12 = 12. Since 1x12 = 12, 12 and 1 are factors of 12, so 12 is a factor of 12. Since all whole numbers (n) can be written as n*1 = n, all whole numbers are factors of themselves.
What whole number less than 150 has odd number of factors?
There are 12 numbers less than 150 which have an odd number of factors: 1,4,9,16,25,36,49,64,81,100,121,144.
What is the greatest whole number that MUST be a factor of the sum of any six consecutive positive odd numbers?
Let the first odd number be 2n-5 (n ≥ 3), then the 6 consecutive odd numbers are: 2n-5, 2n-3, 2n-1, 2n+1, 2n+3, 2n+5 And their sum is: 2n-5 + 2n-3 + 2n-1 + 2n+1 + 2n+3 + 2n+5 = 12n The greatest common factor for all n(≥ 3) of 12n is 12. Thus 12 is the greatest whole number that MUST be a factor of the sum of any six consecutive positive odd numbers.
What is the probability of selecting an even number out of the whole numbers 1 through 12?
50%, or 1 out of 2. There are 12 numbers, 6 even and 6 odd, so they have equal chance of being odd or even if one is selected
How can you work out square numbers by using odd numbers only?
12 = 1 22 = 1 + 3 32 = 1 + 3 + 5 and so on. The square of the nth whole number is the sum of the first n odd numbers.
Is the greatest common factor always even?
No. If at least one of the numbers odd, then it does not have a factor of 2 and so all common factors cannot be divisible by 2 (ie must be odd), and so the greatest of them must also be odd. For example gcf{12, 15) = 3
What are the odd factors of 12?
The factors of 12 are 1, 2, 3, 4, 6, and 12. The odd factors of 12 are the factors that are not divisible by 2, which are 1, 3, and 12. These odd factors are numbers that can be multiplied together to give the number 12 without involving the number 2.
Can you write an odd factor of 12?
1 and 3
