no.
If a number is not divisible by 3 then it is not divisible by 9.
It is impossible since 3 can already go into 9.
To check for divisibility by 9 sum the digits of the number and if this sum is divisible by 9 then so is the original number. For 32643: 3 + 2 + 6 + 4 + 3 = 18 which is divisible by 9 so 32643 is divisible by 9. As 9 = 3 × 3, any number divisible by 9 is also divisible by 3, thus as 32643 is divisible by 9 it is also divisible by 3. However, for completeness: to check for divisibility by 3 sum the digits of the number and if this sum is divisible by 3 then so is the original number. For 32643: 3 + 2 + 6 + 4 + 3 = 18 which is divisible by 3 so 32643 is divisible by 3.
Any that are divisible by 9 are also divisible by 3.
1,377 is divisible by: 1, 3, 9, 17, 27, 51, 81, 153, 459, 1377.
no.
1377 Nice short cut you may wish to use if a number is divisible by 9 then if you add up all it;s digis you get a number divisible by 9 so in this case 1 + 3 + 7 + 7 = 18 where as the original number 1 + 3 + 8 + 2 = 14 which is not divisiable by 9 Enjoy
The factors of 1377 are: 1 3 9 17 27 51 81 153 459 1377 The prime factors are: 3, 17
1, 3, 9, 17, 27, 51, 81, 153, 459, 1377
All numbers divisible by 3 are NOT divisible by 9. As an example, 6, which is divisible by 3, is not divisible by 9. However, all numbers divisible by 9 are also divisible by 3 because 9 is divisible by 3.
9 is divisible by both 3 and 9
Three is divisible by 3 and 9.
If a number is not divisible by 3 then it is not divisible by 9.
NO. 1110 is not divisible by 9. A number is divisible by 9 if the sum of its digits is divisible by 9. 1110 = 1 + 1 + 1 + 0 = 3 (3 is not divisible by 9, thus, 1110 is not divisible by 9.)
it's divisible by 3 = 205. but 615 is not divisible by 9
All numbers divisible by 9 are divisible by 3; since 9 = 3 x 3 all multiples of 9 are also multiples of 3. However, all numbers divisible by 3 are not divisible by 9, eg 6 = 2 x 3 but 6 is not divisible by 9 (since 6 is not a multiple of 9) - it only takes one counter example to disprove a theory.
