Given numbers are 815,428,330,631,407
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,428,330,631,407 is 268748717820.
Find LCM of 815,428,330,631,407 with Prime Factorization
| 2 | 815, 428, 330, 631, 407 |
| 5 | 815, 214, 165, 631, 407 |
| 11 | 163, 214, 33, 631, 407 |
| 163, 214, 3, 631, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 163 x 214 x 3 x 631 x 37 = 268748717820
Therefore, the lowest common multiple of 815,428,330,631,407 is 268748717820.
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.
815 x 428 x 330 x 631 x 407 = 29562358960200
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.
815 : 1, 5, 163, 815
428 : 1, 2, 4, 107, 214, 428
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
631 : 1, 631
407 : 1, 11, 37, 407
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,428,330,631,407, is 1.
Now, the common factors can be found like this.
815:5x 163
428:2x 2x 107
330:2x 3x 5x 11
631:631
407:11x 37
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 11 = 110
Therefore, the value for common factors is 110.
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 = 29562358960200/(1x110)
LCM = 29562358960200/110
LCM = 268748717820
Thus, we can understand that the LCM of 815,428,330,631,407 is 268748717820.
