Given numbers are 391,801,988,940,329
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,801,988,940,329 is 509016804660.
Find LCM of 391,801,988,940,329 with Prime Factorization
| 2 | 391, 801, 988, 940, 329 |
| 2 | 391, 801, 494, 470, 329 |
| 47 | 391, 801, 247, 235, 329 |
| 391, 801, 247, 5, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 47 x 391 x 801 x 247 x 5 x 7 = 509016804660
Therefore, the lowest common multiple of 391,801,988,940,329 is 509016804660.
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.
391 x 801 x 988 x 940 x 329 = 95695159276080
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.
391 : 1, 17, 23, 391
801 : 1, 3, 9, 89, 267, 801
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
329 : 1, 7, 47, 329
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,801,988,940,329, is 1.
Now, the common factors can be found like this.
391:17x 23
801:3x 3x 89
988:2x 2x 13x 19
940:2x 2x 5x 47
329:7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 47 = 188
Therefore, the value for common factors is 188.
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 = 95695159276080/(1x188)
LCM = 95695159276080/188
LCM = 509016804660
Thus, we can understand that the LCM of 391,801,988,940,329 is 509016804660.
