Since 5 is a odd number and 46 is even, the only number that can go into both evenly is 1.
Well both the hundred places are different so u would know that comparing it would be that the 738 is bigger than 645
On a supply and demand graph you would see that the supply would meet the demand at the central point creating a secure system. However, this could change for the better or worse, compared to how "popular" the item is in the market.
