2 x 2 x 5 = 20
2 x 2 x 5 x 47 = 940, the LCM
It doesn't matter which method you use. You still need at least two numbers to find an LCM. There is no LCM of 20.
The LCM of these numbers is 740. LCM is Least Common Multiple.
LCM of 5, 20, 24 = 120The prime factorization of:5 = 5The prime factorization of 20=5 * 2 * 2The prime factorization of 24=..... 2 * 2 * 2 * 3The LCM=5 *2*2 * 2 * 3 = 120
2 x 2 x 5 = 20 The LCM is 20wy.
20/2=10/2=5 5*2*2 equals prime factorization of 20.
NO. The LCM of 5 and 20 is 20.Prime Factorization of:5 = 520 = 5 * 2 * 2=============LCM = 5 * 2 * 2 = 20
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.
prime factorization of each: 2x3 , 3x5, 2x2x5 so LCM = 2x2x3x5 = 60
If it's the lowest Common Multiple (LCM) of 12, 20, 24 and 32 that you're after, I think it's 480 (but my maths is a little rusty)
The prime factorization of 20 is: 2 × 2 × 5
Prime factorization of 20 in exponential form is: 22x5
180 is the LCM of 90 and 20. Prime Factorization of: 90 = 2 * 3 * 3 * 5 20 = 2...........* 5 * 2 ============= LCM= 2 * 3 * 3 * 5 * 2 = 180
