divide the number by 4, 6 , or 8 and if it come out to be a whole number it is a factor of it.
4
The number is 12. 12 ÷ 2 = 6 6 - 4 = 2
It is: 12
Before trying to divide this number by all the given factors. Note 1' It's an even number so will divide by '2' 2' It will NOT divide by '5' because it does not end in '5' or '0' 3' It will not divide by '10' because it does not end in 'zero'. 4' it will not divide by '9' , because the digits do not SUM to '9' (5 + 1 + 4 = 10) So we are left with 2,3,4,6. to attempt division. Hence 2)514 = 257 OK!!! 3)514 = 171 remainder '1' ; Does not divide by '3' 4)514 = 128 remainder '2' ; Does not divide by '4' 6)514 = 85 remainder '4' ; does not divide by '6'. NB One other critical prime number to try is '7' Hence 7)514 = 73 remainder '3' So it does not divide by '7'. So out of the list of factors, only '2' will divide into '514'.
The number one.
6
divide the number by 4, 6 , or 8 and if it come out to be a whole number it is a factor of it.

24
The number is 12. 12 ÷ 2 = 6 6 - 4 = 2
60
divide the number by three then double it. Divide the number by 3 and multiply by 2. Example: 2/3 of 6 is worked out as 6 divided by 3 = 2, then multiply by 2 = 4. So 2/3 of 6 = 4
assume dividing into whole number if you divide by 4 then remainder will be 0,1,2, or 3 by 6 then remainder will be 0,1,2,3,4 or 5 by 9 then remainder will be 0,1,2,3,4,5,6,7 or 8
It is: 12

The Least Common Multiple (LCM) is the smallest number that two or more numbers will divide into evenly and 12 is the smallest number that both 4 and 6 divide into evenly.
