Answer 3

hi

this number is divisible by all the above numbers because

any number ending with 2,4,6,8,0 is divisible by 2

any number is a multiple of 4 will be divisible by 4

any number ending with 0/ 5 will be divisible by 5

any number if it is divisible by 3 will divisible by 6 and 9 too

any number ending with 0 is always divisible by 10.
