Understanding the Number 74
What Kind of Number Is It?
Seventy-four is known as a composite number. This means it has more than two factors (numbers that divide into it evenly). The factors of 74 are 1, 2, 37, and 74. For example, if you have 74 cookies, you could share them equally among 2 friends (each gets 37) or 37 friends (each gets 2).
Seventy-four can also be written as the sum of two perfect squares. A perfect square is a number you get by multiplying a whole number by itself (like 5x5=25). For 74, it's 5 squared plus 7 squared:
- 5 x 5 = 25
- 7 x 7 = 49
- 25 + 49 = 74
74 in Science
In science, 74 is the atomic number of an important metal called Tungsten. Tungsten is a very strong and dense metal. It has the highest melting point of all metals, which means it needs a lot of heat to turn into a liquid. Because of this, tungsten is often used to make the filaments (the tiny wires that glow) inside old-fashioned light bulbs. It's also used in tools that need to be very hard, like drills.
