Example: 30 and 42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Combine the factors, eliminating duplicates.
2 x 3 x 5 x 7 = 210, the LCM
Just write a method or function that calculates the LCM for two numbers at a time. Then calculate the LCM for the first two numbers, get the LCM of the result with the third number, etc.Just write a method or function that calculates the LCM for two numbers at a time.

You need at least two numbers to find an LCM.
The LCM of one number is itself. LCM involves two or more numbers.
To create a flowchart for finding the Least Common Multiple (LCM) of two numbers, start with inputting the two numbers. Then, calculate the Greatest Common Divisor (GCD) of these numbers using the Euclidean algorithm. Next, apply the formula LCM(a, b) = (a * b) / GCD(a, b) to find the LCM. Finally, output the LCM result.
For this you will need a couple of helper algorithms. The first is the GCD (greatest common divisor) which is expressed as follows:procedure GCD (a, b) isinput: natural numbers a and bwhile ab doif a>blet a be a-belselet b be b-aend ifend whilereturn aThe second algorithm is the LCM (least common multiple) of two numbers:procedure LCM (a, b) isinput: natural numbers a and b return (a*b) / GCD (a, b)Now that you can calculate the GCD and LCM of any two natural numbers, you can calculate the LCM of any three natural numbers as follows:procedure LCM3 (a, b, c) isinput: natural numbers a, b and c return LCM (LCM (a, b), c)Note that the LCM of three numbers first calculates the LCM of two of those numbers (a and b) and then calculates the LCM of that result along with the third number (c). That is, if the three numbers were 8, 9 and 21, the LCM of 8 and 9 is 72 and the LCM of 72 and 21 is 504. Thus the LCM of 8, 9 and 21 is 504.
The LCM of two numbers is sometimes the product of the two numbers.
The HCF is always a factor of the LCM of two numbers. The HCF is a factor of both the numbers which are factors of their LCM. Thus the HCF is also a factor of the LCM of the two numbers.
The LCM of 28 and 16 is 112 The LCM of 2, 8 and 16 is 16
No, the only way the GCF and LCM of two numbers can be the same is if the numbers are the same.
To calculate the GCD (Greatest Common Divisor) on the Casio fx-991ES, use the gcd function by entering the two numbers followed by SHIFT and gcd. For the LCM (Least Common Multiple), use the lcm function in a similar way: input the two numbers and then press SHIFT followed by lcm. The calculator will display the results for both GCD and LCM directly on the screen.
The LCM is defined as being a positive integer. Ignore the negative signs. Calculate as if everything's positive.
Yes,LCM of two numbers is their product.
