The same as with 2. Example: 30, 42 and 70
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
2 x 5 x 7 = 70
Combine the highest amount of each factor.
2 x 3 x 5 x 7 = 210, the LCM
Find the lcm of the first two and then find the lcm of that number and the third.
Example:Find the LCM of 4, 6, and15.
The LCM of 4 and 6 is 12 and the LCM of 12 and 15 is 60, so the answer if 60.
First take HCF (highest common factor) of all numbers and save this in a variable then take another variable and multiply all these numbers and then dived the second and first variable .This will be the LCM of numbers. Hint: For finding HCF use this code for two variable and convert it for four variables int hcf(int first,int second)
{
int rem=0;
int div=first;
int divd=second;
if (first>second)
{
do
{
rem=divd%div;
if (rem==0)
break;
divd=div;
div=rem;
}while (rem!=0);
return div;
}
else
{
div=second;
divd=first;
}
do
{
rem=divd%div;
if(rem==0)
break;
divd=div;
div=rem;
}while (rem!=0);
return div;
}
Factor each number down to its primes, then compare the lists for the smallest number in all four lists
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
Find the LCM of the first two and then find the LCM of that number and the third.
Example:Find the LCM of 4, 6, and15.
The LCM of 4 and 6 is 12 and the LCM of 12 and 15 is 60, so the answer if 60.
The LCM of 45 and 4 is 60. The LCM of 4 and 54 is 108. You need at least two numbers to find an LCM.
You need at least two numbers to find an LCM. If that's 3 and 14, the answer is 42.
