Consider the complying with numbers to discover whether the numbers space divisible or not divisible by 3:

(i) 54

Sum of every the number of 54 = 5 + 4 = 9, i beg your pardon is divisible through 3.

Hence, 54 is divisible through 3.

 

(ii) 73

Sum of every the digits of 73 = 7 + 3 = 10, i beg your pardon is no divisible by 3.

Hence, 73 is not divisible by 3.


(iii) 137

Sum of all the digits of 137 = 1 + 3 + 7 = 11, i beg your pardon is notdivisible by 3.

Hence, 137 is no divisible by 3.

 

(iv) 231

Sum of every the number of 231 = 2 + 3 + 1 = 6, i beg your pardon isdivisible by 3.

Hence, 231 is divisible by 3.

 

(v) 194

Sum of every the number of 194 = 1 + 9 + 4 = 14, i m sorry 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 through 3.

Hence, 54 is divisible through 3.

 

(vii) 171

Sum of all the number of 171 = 1 + 7 + 1 = 9, i m sorry isdivisible by 3.

Hence, 171 is divisible by 3.

 

(viii) 277

Sum of every the digits of 277 = 2 + 7 + 7 = 16, which is notdivisible by 3.

Hence, 277 is no divisible through 3.

 

(ix) 276

Sum of all the digits of 276 = 2 + 7 + 6 = 15, i m sorry isdivisible through 3.

Hence, 276 is divisible by 3.

 

(x) 179

Sum of every the number of 179 = 1 + 7 + 9 = 17, i m sorry is notdivisible through 3.

Hence, 179 is not divisible through 3.
