The LCM of 238,598,345,667,391 is 30955470.
Find LCM of 238,598,345,667,391 with Prime Factorization
| 2 | 238, 598, 345, 667, 391 |
| 17 | 119, 299, 345, 667, 391 |
| 23 | 7, 299, 345, 667, 23 |
| 7, 13, 15, 29, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 23 x 7 x 13 x 15 x 29 x 1 = 30955470
Therefore, the lowest common multiple of 238,598,345,667,391 is 30955470.
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.
238 x 598 x 345 x 667 x 391 = 12805596918660
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.
238 : 1, 2, 7, 14, 17, 34, 119, 238
598 : 1, 2, 13, 23, 26, 46, 299, 598
345 : 1, 3, 5, 15, 23, 69, 115, 345
667 : 1, 23, 29, 667
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,598,345,667,391, is 1.
Now, the common factors can be found like this.
238:2x 7x 17
598:2x 13x 23
345:3x 5x 23
667:23x 29
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 23x 23x 23 = 413678
Therefore, the value for common factors is 413678.
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 = 12805596918660/(1x413678)
LCM = 12805596918660/413678
LCM = 30955470
Thus, we can understand that the LCM of 238,598,345,667,391 is 30955470.
