My Special Number Project
I chose this number because: I get to do what I want to do.
My num. is the product of:
1x18,2x9,3x6. Because you can multiply them to get my number (18).
To find the LCM of 2 numbers you can also use the long L method and list the factors out.
The factors of 18 is/are:
1,2,3,6,9,18. Because if you multiply 1x18=18, 2x9=18,3x6=18.
The methods i used are/were: "the long L" method and listing the numbers out.
My number is even because
you can divide 2 into your number and a whole number without any remainders.
The 1st 10 multiples of my number is/are:
18,36,54,72,90,108,126,144,162,180.
My number is composite because:
you can multiply other numbers besides
1 and itself together to get that number.
1x18,2x8,3x6. they would make a rectangle.
My num. is divisible by 2,3,6,9. because you can divide these numbers evenly.
Proper numbers
2,3,6,9
an exponent tells you how many times to multiply a num.
