What are the rules to divisibility by 3 rules?
If the digits of a number add up to a number divisible by three, it's divisible by three. Ex. Is 4,895 divisible by 3? 4+8+9+5=26 26 is not divisible by 3 No. Is 246 divisible by 3? 2+4+6=12 12 is divisible by 3 Yes!
Is the number 26 divisible by 2 3 5 or 9 How do you know?
To be divisible by 2 the number must be even, that is its last digit must be 2, 4, 6, 8, or 0; the last digit of 26 is 6 which is one of {2, 4, 6, 8, 0} so 26 is even and divisible by 2. To be divisible by 3 sum the digits of the number; if this sum is divisible by 3 then the original number is divisible by 3. The test can be repeated on the sum until a single digit remains, in which case if this single digit is 3, 6, or 9 then the original number is divisible by 3; For 26: 2 + 6 = 8 which is not one of {3, 6, 9} so 26 is not divisible by 3. To be divisible by 5 the last digit must be a 0 or 5; the last digit of 26 is a 6 which is not 0 nor 5, so 26 is not divisible by 5. To be divisible by 9 sum the digits of the number; if this sum is divisible by 9 then the original number is divisible by 9. The test can be repeated on the sum until a single digit remains, in which case if this single digit is 9 then the original number is divisible by 9; For 26: 2 + 6 = 8 which is not 9 so 26 is not divisible by 9. 26 is divisible by 2 but not divisible by 3, 5 nor 9.
Is 26 divisible by 2 and 3?
2, yes. 3, no.
Is 26 divisible by 9?
26 is not divisible by 9 because the sum of the digits is not divisible by
Is 26 divisible by 10?
No. 26 is not evenly divisible by ten. ----------------------------------------------------------------- All multiples of 10 end in a zero To be divisible by 10, the last digit must by a 0 The last digit of 26 is a 6 which is NOT a 0, so 26 is NOT divisible by 10.
