What is the LCM of 100 and 130?
Find the LCM by finding prime factorization of both numbers:100 = 2 * 2 * 5 * 5130 = 2 * 5 * 13Then, count each pair of prime numbers. The two factorizations have two pairs of prime numbers: one pair of 2's and one pair of 5's (pairs are bolded, above):Paired primes: 2, 5Next, count the remaining primes and multiply them with the paired primes.Paired primes: 2, 5Unpaired primes: 2, 5, 13The LCM of 100 and 130 is2 * 2 * 5 * 5 * 13 = 1300

Prime numbers and LCM?
LCM is the multiple of the highest power of prime factors of two or more numbers. Since prime numbers have no other factors than themselves, the LCM of two or more prime numbers is their product. As an example, the LCM of 3, 5, and 53 is 3 x 5 x 53 = 795.

Which two numbers have the LCM of 1260?
The least common multiple (LCM) of two numbers is the smallest number that is a multiple of both numbers. To find the two numbers with an LCM of 1260, we need to factorize 1260 into its prime factors, which are 2, 2, 3, 3, 5, and 7. We then pair these prime factors to form two numbers, such as 2 x 2 x 3 x 5 = 60 and 3 x 7 = 21. Therefore, the two numbers with an LCM of 1260 are 60 and 21.
What is the LCM for 5 and 8?
40 is the LCM of 5 and 8. If two numbers are relatively prime ( have no divisors in common, the LCM is just their product. )
How can you use the prime factorization of two numbers to find the LCM?
You can use the numbers in common in the prime factorization to find the LCM (least common multiple of two numbers). Multiply all the prime factors together, but if the two numbers have a prime factor in common, only use that number once. Here are a few examples: Find the LCM of 40 and 35: The prime factorization of 40 is 2*2*2*5. The prime factorization of 35 is 5*7. The prime factorization both have a 5 in common, so you only need one five. The LCM then is 2*2*2*7*5 = 280. Find the LCM of 24 and 20: 24 = 2*2*2*3. 20 = 2*2*5. The prime factorization have two twos in common, so you only need one two from each pair. You will still need another 2 since the third 2 in the prime factorization of 24 does not have a pair in the factorization of 20. The LCM then is 2*2*2*3*5 = 120. Find the LCM of 15 and 4: 15 = 3*5 4 = 2*2 There are no matching pairs between the prime factorization, so find the LCM by multiplying all the numbers together: 2*2*3*5=60 Find the LCM of 60 and 100: 140 = 2*2*3*5 100 = 2*2*5*5 There are two pairs of 2s and a pair of 5. You can think of it like this: 140 = (2*2*5)*3 100 = (2*2*5)*5 The numbers in parentheses are pairs so you only need one of them. In this case, the LCM is (2*2*5)*3*5 = 300.
