Given numbers are 671,838,315,429
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,838,315,429 is 2302610310.
Find LCM of 671,838,315,429 with Prime Factorization
| 3 | 671, 838, 315, 429 |
| 11 | 671, 838, 105, 143 |
| 61, 838, 105, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 61 x 838 x 105 x 13 = 2302610310
Therefore, the lowest common multiple of 671,838,315,429 is 2302610310.
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.
671 x 838 x 315 x 429 = 75986140230
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.
671 : 1, 11, 61, 671
838 : 1, 2, 419, 838
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
429 : 1, 3, 11, 13, 33, 39, 143, 429
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,838,315,429, is 1.
Now, the common factors can be found like this.
671:11x 61
838:2x 419
315:3x 3x 5x 7
429:3x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 75986140230/(1x33)
LCM = 75986140230/33
LCM = 2302610310
Thus, we can understand that the LCM of 671,838,315,429 is 2302610310.
