Question 1:
What is the prime factorization of 1332?
Question 2:
What is the gcd and lcm of 240 and 840?
Question 3:
Is 133 prime? What about 103? How did you find out that it is/is not (without looking it up.)
Question 4:
What is the remainder when 4803925 is divided by 2? What is it when it is divided by 3? By 5? By 13?
How did you figure each of these out?

Q1: 1332
2 x 666 ZOMG 666, THE NUMBER OF THE BEAST :O
2 x 333
3 x 111
3 x 37
2^2 x 3^2 x 37

Q2: GCD and LCM 240 and 840
GCD: 840-240=600
600- 240=360
360-240=120
240-120=120
LCM: 2^4 x 3 x 5 x 7 = 1680

Q3: 133 isn't prime; because I'm good like that and I checked it with numberrsss
103 is prime; same as the above reason

Q4: 4803925/2 = 2401962.5
4803925/3 = 1601308.3(repeating)
4803925/5 = 960785.0
4803925/13 = 369532.692
how did I figure them out? I used a calculator of course
