You are watching: A number is divisible by 3 if the sum of the digits of the number is divisible by 3
Consider the following numbers to discover whether the numbers are divisible or not divisible by 3:
(i) 54
Sum of all the number of 54 = 5 + 4 = 9, i m sorry is divisible through 3.
Hence, 54 is divisible by 3.
(ii) 73
Sum of every the number of 73 = 7 + 3 = 10, i beg your pardon is not divisible by 3.
Hence, 73 is no divisible by 3.
(iii) 137
Sum of every the digits of 137 = 1 + 3 + 7 = 11, which is notdivisible by 3.
Hence, 137 is no divisible by 3.
(iv) 231
Sum of every the number of 231 = 2 + 3 + 1 = 6, which isdivisible by 3.
Hence, 231 is divisible through 3.
(v) 194
Sum of every the number of 194 = 1 + 9 + 4 = 14, which is notdivisible by 3.
Hence, 194 is no divisible by 3.
(vi) 153
Sum of all the digits of 153 = 1 + 5 + 3 = 9, which isdivisible by 3.
Hence, 54 is divisible by 3.
(vii) 171
Sum of every the digits of 171 = 1 + 7 + 1 = 9, which isdivisible through 3.
Hence, 171 is divisible through 3.
(viii) 277
Sum of all the number of 277 = 2 + 7 + 7 = 16, i beg your pardon is notdivisible by 3.
Hence, 277 is no divisible through 3.
(ix) 276
Sum of all the number of 276 = 2 + 7 + 6 = 15, i beg your pardon isdivisible by 3.
Hence, 276 is divisible by 3.
(x) 179
Sum of all the digits of 179 = 1 + 7 + 9 = 17, i m sorry is notdivisible by 3.
Hence, 179 is not divisible through 3.
