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?
The answer is a^2b^2, because the smallest exponent of the a's is 2 and the same thing with the b's. Therefore, that's the LCM (or least common multiple), because it is the smallest value the two terms share with one another. **When writing an exponent on a computer, you use a carrot (^) to represent the exponent.
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.

How you do you find the exponent when is divided in scientific notation?
If the exponent of the numerator is a and the exponent of the denominator is b then the crude exponent of their quotient is a-b. However, if the mantissa of the quotient is less than 1 then it needs to be brought into the range [1, 10) and in doing that, the exponent will become a-b-1.
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))
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-b and b-a?
If A and B have no common factors other than one, the LCM is their product.
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 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
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.
