First time I have done prime factors in long time.
How do you factor 612 into prime factors?
Thanks for any help and if you could explain how you did it.
Keep dividing by prime factors until you can't any longer.
612 = 2 * 306
= 2 * 2 * 153
Note that 1+5+3 is divisible by 3
= 2 * 2 * 3 * 51
Note that 5+1 is divisible by 3
= 2 * 2 * 3 * 3 * 17
17 is prime, you are done.
Keep dividing by prime numbers until you get a prime number.
612 / 2 = 306
306 / 2 = 153
153 / 3 = 51
51 / 3 = 17
Answer: 2 * 2 * 3 * 3 * 17
You divide the number by the lowest prime number you can:
612/2 = 306
Then do the same with the answer:
306/2 = 153
Then again until you get a prime number as the answer:
153/3 = 45
45/3 = 15
15/3 = 5
Then you look at all the prime numbers you've divided by and multiply them together, along with the final answer. 2(squared) x 3(cubed) x 5
Hope this helped!
612 = (2^2)*(3^2)*17
2 * 306
2* 153
3*51
3 * 17
2*2*3*3*17
