The LCM of 415,418,476,747,920 is 17092346040.
Find LCM of 415,418,476,747,920 with Prime Factorization
| 2 | 415, 418, 476, 747, 920 |
| 2 | 415, 209, 238, 747, 460 |
| 5 | 415, 209, 119, 747, 230 |
| 83 | 83, 209, 119, 747, 46 |
| 1, 209, 119, 9, 46 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 83 x 1 x 209 x 119 x 9 x 46 = 17092346040
Therefore, the lowest common multiple of 415,418,476,747,920 is 17092346040.
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.
415 x 418 x 476 x 747 x 920 = 56746588852800
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.
415 : 1, 5, 83, 415
418 : 1, 2, 11, 19, 22, 38, 209, 418
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
747 : 1, 3, 9, 83, 249, 747
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 415,418,476,747,920, is 1.
Now, the common factors can be found like this.
415:5x 83
418:2x 11x 19
476:2x 2x 7x 17
747:3x 3x 83
920:2x 2x 2x 5x 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 2x 2x 5x 83 = 3320
Therefore, the value for common factors is 3320.
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 = 56746588852800/(1x3320)
LCM = 56746588852800/3320
LCM = 17092346040
Thus, we can understand that the LCM of 415,418,476,747,920 is 17092346040.
