Show the divisibility for 143 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 0,2,4,6,8The last digit of 143 is 3
Since 3 is not equal to 0,2,4,6,8, then 143 is not divisible by 2
Divisibililty Check for 3
A number is divisible by 3 if the sum of it's digits ends is divisible by 3The sum of the digits for 143 is 1 + 4 + 3 = 8
Since 8 is not divisible by 3, then 143 is not divisible by 3
Divisibililty Check for 4
A number is divisible by 4 if the last two digits are divisible by 4The last 2 digits of 143 are 43
Since 43 is not divisible by 4, then 143 is not divisible by 4
Divisibililty Check for 5
A number is divisible by 5 if it ends with a 0 or 5The last digit of 143 is 3
Since 3 is not equal to 0 or 5, then 143 is not divisible by 5
Divisibililty Check for 6
A number is divisible by 6 if it is divisible by both 2 and 3Since 143 is not divisible by 2 and 3, then 143 is not divisible by 6
Divisibililty Check for 7
To see if 143 is divisible by 7, we multiply each respective digit by 1,3,2,6,4,5 working backwards and repeat as necessary3(1) + 4(3) + 1(2) = 18
Since 18 is not divisible by 7, then 143 is not divisible by 7
Divisibililty Check for 8
A number is divisible by 8 if the last three digits are divisible by 8The last 3 digits of 143 are 143
Since 143 is not divisible by 8, then 143 is not 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 143 is 1 + 4 + 3 = 8
Since 8 is not divisible by 9, then 143 is not divisible by 9
Divisibililty Check for 10
A number is divisible by 10 if it ends with a 0The last digit of 143 is 3
Since 3 is not equal to 0, then 143 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:
143
1 + 3
Odd Sum = 4
Sum the even digits:
143
4
Even Sum = 4
Take the difference of the odd sum and the even sum:
Δ = Odd Sum - Even Sum
Δ = 4 - 4
Δ = 0
Divisibility Check:
Because Δ = 0, 143 is divisible by 11

In summary, 143 is divisible by (11)
