Given numbers are 380,391,816,602,801
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 380,391,816,602,801 is 143291146320.
Find LCM of 380,391,816,602,801 with Prime Factorization
| 2 | 380, 391, 816, 602, 801 |
| 2 | 190, 391, 408, 301, 801 |
| 3 | 95, 391, 204, 301, 801 |
| 17 | 95, 391, 68, 301, 267 |
| 95, 23, 4, 301, 267 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 95 x 23 x 4 x 301 x 267 = 143291146320
Therefore, the lowest common multiple of 380,391,816,602,801 is 143291146320.
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.
380 x 391 x 816 x 602 x 801 = 58462787698560
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.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
391 : 1, 17, 23, 391
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
602 : 1, 2, 7, 14, 43, 86, 301, 602
801 : 1, 3, 9, 89, 267, 801
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,391,816,602,801, is 1.
Now, the common factors can be found like this.
380:2x 2x 5x 19
391:17x 23
816:2x 2x 2x 2x 3x 17
602:2x 7x 43
801:3x 3x 89
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 2x 3x 17 = 408
Therefore, the value for common factors is 408.
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 = 58462787698560/(1x408)
LCM = 58462787698560/408
LCM = 143291146320
Thus, we can understand that the LCM of 380,391,816,602,801 is 143291146320.
