Given numbers are 115,815,626,215,394
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 115,815,626,215,394 is 99401848270.
Find LCM of 115,815,626,215,394 with Prime Factorization
| 2 | 115, 815, 626, 215, 394 |
| 5 | 115, 815, 313, 215, 197 |
| 23, 163, 313, 43, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 163 x 313 x 43 x 197 = 99401848270
Therefore, the lowest common multiple of 115,815,626,215,394 is 99401848270.
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.
115 x 815 x 626 x 215 x 394 = 4970092413500
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.
115 : 1, 5, 23, 115
815 : 1, 5, 163, 815
626 : 1, 2, 313, 626
215 : 1, 5, 43, 215
394 : 1, 2, 197, 394
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,815,626,215,394, is 1.
Now, the common factors can be found like this.
115:5x 23
815:5x 163
626:2x 313
215:5x 43
394:2x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5 = 50
Therefore, the value for common factors is 50.
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 = 4970092413500/(1x50)
LCM = 4970092413500/50
LCM = 99401848270
Thus, we can understand that the LCM of 115,815,626,215,394 is 99401848270.
