Math Problem Statement

What is the lowest common multiple (LCM) of F and G? Give your answer as a product of its prime factors in index form.

Solution

Let's find the Lowest Common Multiple (LCM) of the two numbers FF and GG, given their prime factorizations.

The prime factorization of FF is: F=310×113×132F = 3^{10} \times 11^3 \times 13^2

The prime factorization of GG is: G=35×54×7×1112×13G = 3^5 \times 5^4 \times 7 \times 11^{12} \times 13

Steps to find the LCM:

  1. Identify all distinct prime factors involved in both FF and GG:

    • Prime factors are: 3,5,7,11,133, 5, 7, 11, 13
  2. Take the highest power of each prime factor from both factorizations:

    • For 33, the highest power is 3103^{10}.
    • For 55, the highest power is 545^4.
    • For 77, the highest power is 717^1.
    • For 1111, the highest power is 111211^{12}.
    • For 1313, the highest power is 13213^2.
  3. The LCM is the product of all these prime factors raised to their highest powers: LCM(F,G)=310×54×7×1112×132\text{LCM}(F, G) = 3^{10} \times 5^4 \times 7 \times 11^{12} \times 13^2

Thus, the LCM of FF and GG, expressed as the product of its prime factors in index form, is: 310×54×7×1112×132\boxed{3^{10} \times 5^4 \times 7 \times 11^{12} \times 13^2}
