Question

which of the following number are divisible by 7 a. 3784​

Answer 1

Answer:

If you have access to a calculator, the easiest way to figure out if 3784 is divisible by 7 may be to simply enter 3784/7 into the calculator. If the quotient is an integer, then 3784 is divisible by 7.

However, you can also determine if 3784 is divisible by 7 using an alternate method.

Simply multiply the last digit by 2 and then subtract the product from the remaining digits.

If that difference is divisible by 7, then 3784 is divisible by 7.

The last digit in 3784 is 4 and the remaining digits are 378. Thus, the math to determine if 3784 is divisible by 7 using our alternate method is:

378 - (4 x 2) = 370

Since 370 is not divisible by 7, 3784 is also not divisible by 7.

Therefore, the answer to "Is 3784 Divisible By 7?" is no.

(3784 / 7 = 540.571)
