Given numbers are 323,820,578,371
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 323,820,578,371 is 1670472020.
Find LCM of 323,820,578,371 with Prime Factorization
| 2 | 323, 820, 578, 371 |
| 17 | 323, 410, 289, 371 |
| 19, 410, 17, 371 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 19 x 410 x 17 x 371 = 1670472020
Therefore, the lowest common multiple of 323,820,578,371 is 1670472020.
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.
323 x 820 x 578 x 371 = 56796048680
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.
323 : 1, 17, 19, 323
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
578 : 1, 2, 17, 34, 289, 578
371 : 1, 7, 53, 371
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 323,820,578,371, is 1.
Now, the common factors can be found like this.
323:17x 19
820:2x 2x 5x 41
578:2x 17x 17
371:7x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17 = 34
Therefore, the value for common factors is 34.
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 = 56796048680/(1x34)
LCM = 56796048680/34
LCM = 1670472020
Thus, we can understand that the LCM of 323,820,578,371 is 1670472020.
