1023456. As it is a 7 digit number, 0 cant be put first. Hence the digit 1 goes first. and then come 0. After that, as there is no repetition allowed, we skip the number 1 and place 2. Then, we go chronologically until we have a total of 7 digits <span />
Euclid's division Lemma states that for any two positive integers ‘a’ and ‘b’ there exist two unique whole numbers ‘q’ and ‘r’ such that , a = bq + r, where 0≤ r < b.
Here, a= Dividend, b= Divisor, q= quotient and r = Remainder.
According to Euclid's division lemma a 3q+r, where 0≤r≤3 and r is an integer.
