Question

how many number up to 5 and divisible by 23​

Answer 1

Answer:

If you are speaking about positive integers only two numbers 23 and 46 are divisible by 23 up to 50.

If zero is considered then Zero is also divisible be 23, (zero is divisible by any number)

If negative integers are also considered, then there will be infinite integers.

Let 23X be all such numbers

And 23X < 50

=> X < 50/23

For every X < 50/23 i.e, we can say, X < 3

Or X = {……., -3, -2, -1, 0, 1, 2}

the numbers will be {……. , -46, -23, 0, 23, 46}
