Find the Smallest 6 digit number which is exactly divisible by 175

The question is reprouduced here.

Find the smallest 6 digit number Which is exactly divisible by 175


smallest 6-digit number= 100000

Hint: smallest 6-digit number is 1 with 0 written 5 times. Smallest 1-digit number is 1. Smallest 2-digit number is 10 , Smallest 3-digit number is 100 and so on .

100000/175
Quotient= 571
Remainder= 75
100 more can divide it exactly and will remain smallest 6 digit number.
Therefore, The required number = 100000+100
=100100

Hint: Remainder is the amount in the dividend (100000). Therefore this excess amount when added to 100 to get the exact dividend divisible by 175.

  1. Dear Sir,
    As you have mentioned already, the smallest 6 digit number is 100000, so any number subtracted from that will be " more small" and become a 5 digit number.
    So, we have to add any number greater that smallest number to get the number divisible by 175 exactly.
    Therefore, 571-75=496 is the number we have to add with 100000 to have 100496 and this is the required number as par the question.
    Thanks,
