Given numbers are 331,489,394,315
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 331,489,394,315 is 6696106830.
Find LCM of 331,489,394,315 with Prime Factorization
| 3 | 331, 489, 394, 315 |
| 331, 163, 394, 105 |
Multiply the prime numbers at the bottom and the left side.
3 x 331 x 163 x 394 x 105 = 6696106830
Therefore, the lowest common multiple of 331,489,394,315 is 6696106830.
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.
331 x 489 x 394 x 315 = 20088320490
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.
331 : 1, 331
489 : 1, 3, 163, 489
394 : 1, 2, 197, 394
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,489,394,315, is 1.
Now, the common factors can be found like this.
331:331
489:3x 163
394:2x 197
315:3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 20088320490/(1x3)
LCM = 20088320490/3
LCM = 6696106830
Thus, we can understand that the LCM of 331,489,394,315 is 6696106830.
