How do you find the LCM with a factor tree?
The factor tree finds the prime factorization. The prime factorization finds the LCM. Example: 30 and 42 Factor them. 30 15,2 5,3,2 42 21,2 7,3,2 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the highest amount of each factor. 2 x 3 x 5 x 7 = 210, the LCM
What is the LCM of 30 and 35?
5 or 1 5 would be the greatest common factor (GCF) but the LCM (Least Common Multiple) is found by either listing factors of both numbers, or by prime factorization. The prime factorization method: 30 = 2*3*5 35 = 5*7 So the LCM = 2*3*5*7 = 210 Note that 210/30 = 7 and 210/35 = 6 so both numbers, 30 and 35 are factors of 210. The listing method: 30,60,90,120,150,180,210 35,70,105,140,175,210 So 210 is the first (least) number that is a multiple of 30 and 35
What is the prime factorization of 30 in exponential form?
30=2 x 3 x 5
How do you get the lowest common denominator?
The easiest way is through prime factorization. Example: 1/30 and 1/42 The lowest common denominator in this case is the LCM of 30 and 42. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 2 x 3 x 5 x 7 = 210, the LCM and the lowest common denominator.
What LCM of 2 3 and 5 and why?
The LCM of 2, 3 and 5 is 30. The LCM of any three relatively prime numbers a, b and c is a*b*c, and here, 2 is a, 3 is b and 5 is c. Since 2, 3 and 5 are relatively prime, the LCM is 2*3*5=30.
What is the LCM of 12 and 30 using prime factorization?
It is: 60
What is the LCM of 15 and 30 using prime factorization?
3 x 5 = 15 2 x 3 x 5 = 30 2 x 3 x 5 = 30, the LCM
What is TM of 70 and 30 using prime factorization?
The prime factorization of 30 is 2 x 3 x 5. The prime factorization of 70 is 2 x 5 x 7. An online source lists thirty-seven possible definitions for TM, none of which seem to pertain to this application. On the off chance you meant LCM, 2 x 3 x 5 x 7 = 210, the LCM
What is the LCM of 30 and 87 using prime factorization?
2 x 3 x 5 = 30 3 x 29 = 87 2 x 3 x 5 x 29 = 870, the LCM
What is the least common multiple of 25 and 30?
The LCM of 25 and 30 is: 150The prime factorization of 25 = 5x5The prime factorization of 30 = 2x3x5GCF = 5But, what is the use of calculating GCF here?Answer: If we divide the product of 25 and 30 by GCF then the result is LCM.Product of 25 & 30 = 25x30 = 750So, LCM = 750/5 =150Least Common Multiple (LCM) for 25 30 is 150
What is the lcm of 30 and 50 using prime factorization?
2 x 3 x 5 = 30 2 x 5 x 5 = 50 2 x 3 x 5 x 5 = 150, the LCM
What Is the LCM of 30 and 70 using prime factorization?
2 x 3 x 5 = 30 2 x 5 x 7 = 70 2 x 3 x 5 x 7 = 210, the LCM
How do you find the LCM without using prime factorization?
Example: 30 and 42 List the multiples. 30, 60, 90, 120, 150, 180, 210, 240 42, 84, 126, 168, 210, 252 The LCM is 210.
What is the lcm of 12, 30 and 150?
To find the LCM of 12, 30, and 150, we need to decompose the numbers into their prime factors. The prime factorization of 12 is 2^2 * 3, the prime factorization of 30 is 2 * 3 * 5, and the prime factorization of 150 is 2 * 3 * 5^2. Now, we need to choose the common and uncommon prime factors with the highest exponent. The common prime factors are 2 and 3, and the uncommon prime factors are 5 and 2^2. Therefore, the LCM of 12, 30, and 150 is 2^2 * 3 * 5^2 = 300. [1]
What is the prime factorization of both the numerator and the denominator of the fraction?
Take 30/42, for example. The prime factorization of the numerator (30) is 2 x 3 x 5. The prime factorization of the denominator (42) is 2 x 3 x 7. This will help you find the GCF or the LCM.
How do you find the LCM of 12 and 30 using prime factorization?
