Find the LCM of 321, 214, 807, 115 with the LCM of Two or More Numbers Calculator. Here we are teaching you two different methods through which you can calculate the LCM of 321, 214, 807, 115. So, keep reading to learn more.
Given numbers are 321,214,807,115
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 321,214,807,115 is 19860270.
Find LCM of 321,214,807,115 with Prime Factorization
3 | 321, 214, 807, 115 |
107 | 107, 214, 269, 115 |
1, 2, 269, 115 |
Multiply the prime numbers at the bottom and the left side.
3 x 107 x 1 x 2 x 269 x 115 = 19860270
Therefore, the lowest common multiple of 321,214,807,115 is 19860270.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
321 x 214 x 807 x 115 = 6375146670
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
321 : 1, 3, 107, 321
214 : 1, 2, 107, 214
807 : 1, 3, 269, 807
115 : 1, 5, 23, 115
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,214,807,115, is 1.
Now, the common factors can be found like this.
321:3x 107
214:2x 107
807:3x 269
115:5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 107 = 321
Therefore, the value for common factors is 321.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 6375146670/(1x321)
LCM = 6375146670/321
LCM = 19860270
Thus, we can understand that the LCM of 321,214,807,115 is 19860270.
