Question

One number has a prime factorization of 23.32, and another number has a prime factorization of 22.3°. Which of the

following expressions would equal the greatest common factor of these two numbers?
25.35
23.33
22.32
2.3

Answer 1

Assuming first number is (2^3)(3^2), second number is (2^2)(3^1).

First number: 2 * 2 * 2 * 3 * 3

Second number: 2 * 2 * 3

Both numbers have at least two factors for 2 and one factor for 3.

Their greatest common factor is (2^2)(3).
