What is the formula to find the LCM of three numbers?
Assume a, b and c are integers. The formula of the LCM of three numbers is: p1max(a,b,c)p2max(a,b,c)......prmax(a,b,c), where each pi to the max() tells you the maximum exponent of the prime of one of the terms. For instance: Find the LCM of 2, 3 and 4. 2 = 2 3 = 3 4 = 2² Then, the prime 2 with the max exponent is 2, so select 2². The prime 3 with the max exponent is 1, so select 3. Multiply these values altogether to obtain 2² x 3 = 12.
What the LCM of 14 and 48?
For any two numbers a and b if a is divisible by b then LCM(a,b) is a.48 is divisible by 6, so LCM(48,6) is 48.
How do you use the prime factorizations to find the LCM of a and b?
a and b have no common prime factors. Their LCM is their product.
How do you factor rational expressions with 3 or 4 exponent?
If the rational expressions have large exponent, then you need to factor out this way: (a + b)ⁿ = (a + b)(a + b)...(a + b) [So there are n "(a + b)" factors.] Here are the examples... (a + b)³ = (a + b)(a + b)(a + b) (a + b)4 = (a + b)(a + b)(a + b)(a + b)
What the LCM of 63 and 76?
Factor them. 2 x 2 x b x b = 4b2 2 x 3 x b x b x b = 6b3 Combine the factors, eliminating duplicates. 2 x 2 x 3 x b x b x b = 12b3, the LCM
What is the LCM of a3b2 and a2b5?
To find the least common multiple (LCM) of two terms, we need to identify the highest power of each unique factor present in both terms. In this case, the LCM of a³b² and a²b⁵ would be a³b⁵, as it includes the highest power of both 'a' and 'b' present in either term. Therefore, the LCM of a³b² and a²b⁵ is a³b⁵.
How do you learn about LCM?
LCM means least common multiple. It's the popular math topic to learn in elementary school course and number theory college course.To learn about LCM, you need to factor out each term. Then, select the prime factor with the maximum exponent in either the factors of the first or another. In simplest form:LCM = [a,b] = p1max(a,b)p2max(a,b).....pnmax(a,b) where pi are the prime factors of a and b."max(a,b) of the p's" means that you select the prime factor with the largest exponent out of the whole prime factors for each term you have factored out.
What is the formula to find the LCM of three numbers?

For instance: Find the LCM of 2, 3 and 4. 2 = 2 3 = 3 4 = 2² Then, the prime 2 with the max exponent is 2, so select 2². The prime 3 with the max exponent is 1, so select 3. Multiply these values altogether to obtain 2² x 3 = 12.
Which number is the exponent and which is the base?
If you have ab then a is the base and b the exponent
Is lcm of a and b equals lcm of a and b-a If so why?
The LCM of and b does not equal the LCM of a and b - a.
How can you find the Lowest common denominator of four integers?
lcm(a,b,c,d) = lcm(lcm(a,b,c),d) = lcm(lcm(a,b),lcm(c,d))
Prove that if gcd(a,b)=1, then lcm(a,b)=ab?
gcd(a,b) = 1, Since lcm is the multiple of a and b, a|lcm(a,b) =⇒ lcm(a,b) = ax b|lcm(a,b) =⇒ b|ax =⇒ ax = bq for q∈Z Since gcd(a,b) = 1,b |x and b≤x =⇒ ab ≤ ax ---→ (O1) However, ax is the least common multiple and ab is a common multiple of a and b, ax ≤ ab ---→ (O2) by (O1) and (O2) , ax = ab lcm(a,b) = ab
What is an integral exponent?
If you have a real number,a, and raise it to a power b we say a^b is a times itself b times. That is to say aaaaaaaa...aaa b times. a is the base and b is the exponent. So if b is an integer,... -3,-2,-1,0,1,2,3... ,then we have an integral exponent. Examples are 2^5 and 2^-3. An example that is NOT an integral exponent is 2^(1/2) since 1/2 is not an integer. Dr. ChuckIt means that the exponent is a whole number, for example 3, 0, or -5.
What is the LCM Of a to the second B and B to the second c?
The LCM of a^2b and b^2c is a^2b^2c
What is the LCM for 12 2?
If a is divisible by b, then LCM of a and b is a.Here 12 is divisible by 2. So, LCM of 2 and 12 is 12.
How do you change scientific notation in positive exponent to standard form?
If the exponent is b, then you move the decimal point b places to the right - inserting zeros if necessary.
What is the LCM of 77 and66?
Method for finding LCM of two numbers a and b: LCM(a,b) = Product of a and b/HCF(a,b)Product of 77 and 66 = 77x66HCF(77,66) = 11LCM(77,66) = (77x66)/11 = 66x7 = 462.
