[QUOTE="pickup, post: 635359"] that's cool a nine digit number that times itself equals a number that climbs up to 9 and down again. Did you also know that any multiple of 9 has it's individual digits equal to 9. For example , 72 which is 8 times 9 ,. 7 plus 2 equals 9. the converse is also true, any number whose digits equal 9 is a multiple of nine . and in this case the individual digits of the number 12,345,678,987,654,321 add up to 81 which in turn , it's digits add up to 9. So we have a multiple of 9 based on that rule and sure enough 9 times 1,371,742,109,739,369 equals 12,345,678,987,654,321. Just thought you would like to know [/QUOTE]
