Question

find greatest 6 digit no which exactly divisible by 25 ,30 and 35
​

Answer 1

Answer:

100795 ÷ 25 =4031.8

100795 ÷30=3359.84

100795÷35=2879.85714...

Answer 2

Answer:

first we have to do LCM,

25=5×5

30=2×3×5

35=5×7

LCM=5×2×3×7

=210

Greatest 6 digit number=999999

then we have to divide greatest 6digit number with the LCM

=999999/210

=Quotient=47619

Remainder=9

we want 6digit number exactly divisible by these numbers

hence,

we have to do

subtract remainder from dividend

999999-9=999990

so the greatest 6 digital number which is divisible by 25,30,35 is 999990.
