chetan2u · Answer

Hi,

the moment we see that the last two digits are 00, the number is div by 4..
No need to look any forward..

For some more info in the choices available.. 
 Eliminate 3 and 6 WITHOUT checking for divisiblity by 3.. WHY? 
the number 347,456,500 is an EVEN number, so if the number is div by 3, it will also be div by 6..
Can we have two CORRECT answers .. NO

This question can be easily solved if we know the divisibility rules of numbers given in the options:

3: Sum of the digits should be divisible by 3
4: Last two digits should be divisible by 4
6: The number should be divisible by both 2 and 3
7: We can skip this divisibility rule as it is too complex.

Given number: 347,456,500
Going by the rules, the last two digits are 00, which are divisible by 4
Hence the number is also divisible by 4.
Correct Option: B

rohitsatya · Answer

The question asks which number divides the given number EVENLY 
4 doesn't divide evenly.
Hence, the answer should be E right?

Manonamission · Answer

Use divisibility rules to identify the solution.

500 is divisible by 4

Hence B

Hi all,
The question is to find the number which will divide evenly 347,456,500. Does 4 evenly divide 347,456,500? 4 divides 347,456,500 but not evenly. Help me to understand this.
Thanks in advance.

Bunuel · Answer

Evenly divisible means simply divisible, it's not necessary the result of the division to be even.

DharLog · Answer

Uf, stared at this question and could not understand, what do they want from me.
I have to get used to: 347,456,500 - this is one number, not 3 different.
Why to put ","?

Bunuel · Answer

Some people use a comma (,)to mark every 3 digits. It just keeps track of the digits and makes the numbers easier to read.

. is used to separate howl part from decimal part.

Hope it helps.

mimajit · Answer

This is how i solved

Just by looking at the no it ends with 00 and as know if the last two digits are 00, it is divisible by 4 .We can choose to select B and move on...

we can also straight away rule out option E as we know it is divisible by 4

also just to convince no other no is divisible lets do the divisibility check

3: Sum of the digits should be divisible by 3
4: Last two digits should be divisible by 4
6: The number should be divisible by both 2 and 3
7: We can skip this divisibility rule as it is too complex.

Given number: 347,456,500

The sum of digits is 34 and is not divisible by 3..
 also since it is not divisible by 3 it cant be divisible by 6

RUle for 7 is complex and not tested on GMAT so eliminate
.
Correct Option: B
