If x is the sum of all prime factors of 38, and if y is the sum of all prime factors of 84, what is the value of x-y? Please explain prime factors.
\n" ); document.write( "prime numbers are those which are not divisible by any number other than itself and 1...that is 2,3,5,7,11,13,17,19,23,29 etc...
\n" ); document.write( "ONE IS EXCLUDED BY CONVENTION,THOUGH IT DOES QUALIFY AS PER DEFINITION.
\n" ); document.write( "so if a factor is prime ,then it is called prime factors..ex..
\n" ); document.write( "prime facrors of 4 are 2
\n" ); document.write( "prime facrors of 12 are 2,3...etc....
\n" ); document.write( "prime factors of 38....2,19...their sum is 21=x
\n" ); document.write( "prime factors of 84.....2,3,7,....their sum is 12=y
\n" ); document.write( "x-y=21-12=9
