All numbers except primes themselves can be written as a multiple of two or more primes.
So you just need to try dividing the number by prime numbers. Trying 13 gives 1001 = 13*77 = 13*7*11. 13, 7 and 11 are all prime numbers, so you know you have found the unique prime factorization of 1001.
It is: 789 times 1001 = 789789
500+501, 1000+1, etc
The sum of 1,011 and 1,001 is 2,012. Unless they are binary numbers, in which case 1011 + 1001 = 10100
143 times.
3*69 = 207You could also do the following:1 times 207 equals 2073 times 69 equals 2079 times 23 equals 20723 times 9 equals 20769 times 3 equals 207207 times 1 equals 207
It is: 77 times 13 = 1001
12012 or 12 inches times 1001 feet equals 12012.
