How do you find sets of two numbers if HCF and LCM are known?
You cannot. The numbers 2 and 12 have hcf = 2 and LCM = 12 The numbers 4 and 6 also have hcf = 2 and LCM = 12 So if you just knew the hcf and LCM you would not know which of the two was the required pair.
What is the LCM of 35x to the 8 power and 245x to the 7 power?
Well, let's start by breaking down the numbers and variables. The LCM, or least common multiple, is the smallest multiple that both numbers share. For 35x^8 and 245x^7, we can see that the common factors are 5, 7, and x^7. So, the LCM would be 5 * 7 * x^7, which simplifies to 35x^7.
Find the LCM of 14 and 22?

How do you calculate the LCM of an equation with variables and exponents?
4(x-1)2(x2+6x+8) and 10(x-1)(x+2)(X2+7x+10)
How do you find LCM with variables and exponents?
Example: 3x4y2 and 9x3y5 Treat the whole numbers normally. The LCM of 3 and 9 is 9. Choose the highest value of the variables. In this case, the LCM is 9x4y5
What do you do when you have a variable when trying to find the LCM?
The LCM will contain all factors including variables. Look at coefficients and find their LCM. Then IF several terms have a common factor with a differnt exponent, use that variable with the largest exponent. If a variable appears in only one term, it will still be part of the LCM with its exponent. EX Find LCM for 14s3 and 6 ---- ANSWER --- 42s3 Ex Find Lcm for 3x2y , 4y3, and 7x --- The LCM is 84x2y3 biggest exponents even if not in all terms.
How do you find the LCM of two monomials with variables and exponents?
Example: 3x4y2 and 9x3y5 Treat the whole numbers normally. The LCM of 3 and 9 is 9. Choose the highest value of the variables. In this case, the LCM is 9x4y5
How do you find the LCM of 6a3 and 8a?
Do the numbers first. The LCM of 6 and 8 is 24. Choose the higher of the variables. The LCM of 6a3 and 8a is 24a3
What kind of math operation would you use in finding LCM?
If I was trying to find a least common multiple, I would use multiplication.
How do you find least common multipleand greatest common factor with a number that has variables and exponents next to it?
Do the numerical factors (coefficients) first. For the GCF of the variables, choose the lowest power of each. For the LCM of the variables, choose the highest power of each. Example 6x2y3z4 and 9x3y4z2 The GCF is 3x2y3z2 The LCM is 18x3y4z4
Can 1 be a LCM?
1 can only be an LCM (least common multiple) if the numbers you're trying to find an LCM for are 1 and 1. LCM cannot be smaller than the largest of the numbers you're using.
Why you need LCM and HCF in maths?
It's kind of an inverse relationship. The product of the GCF and LCM of two numbers is the same as the product of the original two numbers, so as the GCF increases, the LCM decreases and vice versa. LCM is divisable by HCF.
What is the LCM of 78 and 442?
The lowest common multiple (LCM) of 442 and 78 is 1,326. To find this, you would go through the multiple of the highest number in the set of numbers that you are trying to find the LCM of. In this case, that number is 442. First you would multiply it by 2 which is 884. Then you would find out if 884 is divisible by 78, which it is not. Now mutiply 442 by 3, which is 1326. It is divisible by 78. So therefore 1,326 is you LCM. With any other set of numbers, you would do the same thing by going down the number line until you get the LCM. P.S. I made it sound more confusing than it actually is lol ^_^ I hope this helped!
How do you find the LCM of 10a6c8 2a7c8 15a8c8?
Factor the coefficients. 2 2 x 5 3 x 5 Combine the factors, eliminating duplicates. Select the higher powers of the variables. The LCM is 30a8c8
What is the LCM of a2b5 plus a3b3?
LCM(a2b5, a3b3) The LCM of both numbers HAS to have the largest coefficient of both variables. For a, it's a3, and for b it is b5. So the LCM is a3b5.
What is the LCM of 81224?
You can not find the LCM of 81224. In order to find a least common multiple, you have to have at least two different numbers. An example would be the LCM for the numbers 81 and 224 is 18144.
