2 x 2 x 5 x 7 x 13 = 1820

2 x 3 x 3 x 3 x 5 x 13 = 3510

2 x 5 x 13 = 130, the GCF

2 x 2 x 3 x 3 x 3 x 5 x 7 x 13 = 49140, the LCM

To find the highest common factor (HCF) and least common multiple (LCM) of 1820 and 3510 using long factorization, we first need to factorize both numbers. The prime factorization of 1820 is 2^2 * 5 * 7 * 13, and the prime factorization of 3510 is 2 * 3^2 * 5 * 13. To find the HCF, we take the minimum power of common prime factors, which is 2 * 5 * 13 = 130. To find the LCM, we take the maximum power of all prime factors, which is 2^2 * 3^2 * 5 * 7 * 13 = 8190.

Well, honey, the HCF (Highest Common Factor) of 1820 and 3510 is 130, and the LCM (Least Common Multiple) is 12660. You can find these bad boys through long factorization, but let's be real, ain't nobody got time for that when you can just use a calculator.
