Algebra.Com's Answer #177610 by Theo(13342)![]() ![]() You can put this solution on YOUR website! since 9 is not a multiple of 4, the smallest number that can be divisible by 4 and 9 has to be a number that is the result of a product of 4 * 9.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "if it is divisible by 4 and 9, then it has to be divisible by factors of 4 and 9.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "that means it is divisible by 2 and 3 as well.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "it should also be divisible by any combination of the factors of 4 and 9.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "since the factors would be 2*2*3*3, then:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "that would be:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "2*2 = 4 \n" ); document.write( "2*3 = 6 \n" ); document.write( "3*3 = 9 \n" ); document.write( "2*2*3 = 12 \n" ); document.write( "2*3*3 = 18\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "4*9 * anything else would yield even more possibilities/.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "example:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "4*9*2 = 72\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "since there's another factor in the mix, 72 should be divisible by even more numbers that are combinations of factors of 2*2*3*3*2\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "those would be:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "2*2 = 4 \n" ); document.write( "2*3 = 6 \n" ); document.write( "3*3 = 9 \n" ); document.write( "2*2*3 = 12 \n" ); document.write( "2*3*3 = 18 \n" ); document.write( "plus: \n" ); document.write( "2*2*2 = 8 \n" ); document.write( "2*2*3*2 = 24 \n" ); document.write( "2*3*3*2 = 36\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
