Find LCM of 393,598,415,621,830 with Prime Factorization
| 2 | 393, 598, 415, 621, 830 |
| 3 | 393, 299, 415, 621, 415 |
| 5 | 131, 299, 415, 207, 415 |
| 23 | 131, 299, 83, 207, 83 |
| 83 | 131, 13, 83, 9, 83 |
| 131, 13, 1, 9, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 83 x 131 x 13 x 1 x 9 x 1 = 877777290
Therefore, the lowest common multiple of 393,598,415,621,830 is 877777290.
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 598 x 415 x 621 x 830 = 50270305398300
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
598 : 1, 2, 13, 23, 26, 46, 299, 598
415 : 1, 5, 83, 415
621 : 1, 3, 9, 23, 27, 69, 207, 621
830 : 1, 2, 5, 10, 83, 166, 415, 830
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,598,415,621,830, is 1.
Now, the common factors can be found like this.
393:3x 131
598:2x 13x 23
415:5x 83
621:3x 3x 3x 23
830:2x 5x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 23x 83 = 57270
Therefore, the value for common factors is 57270.
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 = 50270305398300/(1x57270)
LCM = 50270305398300/57270
LCM = 877777290
Thus, we can understand that the LCM of 393,598,415,621,830 is 877777290.
