Show the divisibility for 248 in terms of 2,3,4,5,6,7,8,9,10,11
Divisibililty Check for 2
A number is divisible by 2 if the last digit ends in 0,2,4,6,8
The last digit of 248 is 8
Since 8 is equal to 0,2,4,6,8, then 248 is divisible by 2
Divisibililty Check for 3
A number is divisible by 3 if the sum of it's digits ends is divisible by 3
The sum of the digits for 248 is 2 + 4 + 8 = 14
Since 14 is not divisible by 3, then 248 is not divisible by 3
Divisibililty Check for 4
A number is divisible by 4 if the last two digits are divisible by 4
The last 2 digits of 248 are 48
Since 48 is divisible by 4, then 248 is divisible by 4
Divisibililty Check for 5
A number is divisible by 5 if it ends with a 0 or 5
The last digit of 248 is 8
Since 8 is not equal to 0 or 5, then 248 is not divisible by 5
Divisibililty Check for 6
A number is divisible by 6 if it is divisible by both 2 and 3
Since 248 is not divisible by 2 and 3, then 248 is not divisible by 6
Divisibililty Check for 7
To see if 248 is divisible by 7, we multiply each respective digit by 1,3,2,6,4,5 working backwards and repeat as necessary
8(1) + 4(3) + 2(2) = 25
Since 25 is not divisible by 7, then 248 is not divisible by 7
Divisibililty Check for 8
A number is divisible by 8 if the last three digits are divisible by 8
The last 3 digits of 248 are 248
Since 248 is divisible by 8, then 248 is divisible by 8
Divisibililty Check for 9
A number is divisible by 9 if the sum of it's digits is divisible by 9.
The sum of the digits for 248 is 2 + 4 + 8 = 14
Since 14 is not divisible by 9, then 248 is not divisible by 9
Divisibililty Check for 10
A number is divisible by 10 if it ends with a 0
The last digit of 248 is 8
Since 8 is not equal to 0, then 248 is not divisible by 10
Divisibililty Check for 11
A number is divisible by 11 if the sum of the odd digits - the sum of the even digits = 0 or is a multiple of 11
Sum the odd digits:
248
2 + 8
Odd Sum = 10
Sum the even digits:
248
4
Even Sum = 4
Take the difference of the odd sum and the even sum:
Δ = Odd Sum - Even Sum
Δ = 10 - 4
Δ = 6
Divisibility Check:
Because Δ / 11 is not an integer = 22.545454545455, then 248 is NOT divisible by 11

In summary, 248 is divisible by (2,4,8)
