6 is divisible by 438 because every number is divisible by any non-zero number. 6/438 = 0.0136986301369863 (repeating 8-digit string).
438/2 = 219 438/3 = 146 438/4 = 109.5 438/6 = 73 so 2 and 3 and 6 are and 4 is not.
Multiples of 9 and 6 are also divisible by three, the reverse is not true. 15 is divisible by 3, but not 6 or 9. 27 is divisible by 3 and 9, but not 6. 12 is divisible by 3 and 6, but not 9. 54 is divisible by 3, 6 and 9.
No, 6 is not divisible by 148. In order for one number to be divisible by another, the first number must be a multiple of the second number. In this case, 6 is not a multiple of 148 as it is much smaller. Therefore, 6 is not divisible by 148.
Yes, 258 is divisible by 6, since 43 x 6 = 258
Using the tests for divisibility:Divisible by 3:Add the digits and if the sum is divisible by 3, so is the original number: 6 + 8 + 4 = 18 which is divisible by 3, so 684 is divisible by 3Divisible by 6:Number is divisible by 2 and 3: Divisible by 2:If the number is even (last digit divisible by 2), then the whole number is divisible by 2. 684 is even so 684 is divisible by 2.Divisible by 3:Already shown above to be divisible by 3. 684 is divisible by both 2 & 3 so 684 is divisible by 6Divisible by 9:Add the digits and if the sum is divisible by 9, so is the original number: 6 + 8 + 4 = 18 which is divisible by 9, so 684 is divisible by 9Thus 684 is divisible by all 3, 6 & 9.
