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.
Adv. as long as you try all primes starting with the smallest you will get the correct answer. Disadv. Time consuming. If you factor using larger numbers you can work faster, but you must remember to factor those as well. Ex Write the prime factorization of 270. You can easily see that 10 x 27 = 270 but neither is prime. Now factor both 10 and 27. 10 = 2 x 5 both are prime 27 = 3x9 but 9 is not prime so 27 = 3x3x3 all are prime So the prime factorization is 2x5x3x3x3 Faster if you just think and don't have to type it all to explain.
It depends on what units you're using. It's 1,500,000 minutes or 90,000,000 seconds.
To convert a fraction to a decimal, you divide the numerator by the denominator - on a calculator, or using long division.
1/8 - 3/4 in per ft depending on which code your using and if this is waste or leader line
Converting a rational number to a decimal using long division. For example if you have a rational number of 2/5 you would set up the equation as 2 divided by 5 which requires long division. The answer to this would then be the decimal number 0.4.
