<P> The process begins by dividing all of the factors by 2 . If any of them divides evenly, write 2 at the top of the table and the result of division by 2 of each factor in the space to the right of each factor and below the 2 . If a number does not divide evenly, just rewrite the number again . If 2 does not divide evenly into any of the numbers, try 3 . </P> <Table> <Tr> <Th> x </Th> <Th> </Th> </Tr> <Tr> <Td> </Td> <Td> </Td> </Tr> <Tr> <Td> 7 </Td> <Td> 7 </Td> </Tr> <Tr> <Td> 12 </Td> <Td> 6 </Td> </Tr> <Tr> <Td> 21 </Td> <Td> 21 </Td> </Tr> <Tr> <Td> 42 </Td> <Td> 21 </Td> </Tr> </Table> <Tr> <Th> x </Th> <Th> </Th> </Tr> <Tr> <Td> </Td> <Td> </Td> </Tr>
