Given numbers are 393,621,897,788,617
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 393,621,897,788,617 is 514182900348.
Find LCM of 393,621,897,788,617 with Prime Factorization
| 3 | 393, 621, 897, 788, 617 |
| 23 | 131, 207, 299, 788, 617 |
| 131, 9, 13, 788, 617 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 131 x 9 x 13 x 788 x 617 = 514182900348
Therefore, the lowest common multiple of 393,621,897,788,617 is 514182900348.
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.
393 x 621 x 897 x 788 x 617 = 106435860372036
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.
393 : 1, 3, 131, 393
621 : 1, 3, 9, 23, 27, 69, 207, 621
897 : 1, 3, 13, 23, 39, 69, 299, 897
788 : 1, 2, 4, 197, 394, 788
617 : 1, 617
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,621,897,788,617, is 1.
Now, the common factors can be found like this.
393:3x 131
621:3x 3x 3x 23
897:3x 13x 23
788:2x 2x 197
617:617
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 23 = 207
Therefore, the value for common factors is 207.
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 = 106435860372036/(1x207)
LCM = 106435860372036/207
LCM = 514182900348
Thus, we can understand that the LCM of 393,621,897,788,617 is 514182900348.
