All nonzero numbers have factors. Some factors are odd numbers. 3 is an odd factor of 12.
There are four odd numbers less that 100 that have 6 factor. This does not compare with even numbers that have 12 factors!
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.
An odd number can't have 12 as a factor. 528 does have 12 as a factor.
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.
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.
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
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.
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.
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!
