Given numbers are 416,440,284,878,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 416,440,284,878,442 is 12123494240.
Find LCM of 416,440,284,878,442 with Prime Factorization
| 2 | 416, 440, 284, 878, 442 |
| 2 | 208, 220, 142, 439, 221 |
| 2 | 104, 110, 71, 439, 221 |
| 13 | 52, 55, 71, 439, 221 |
| 4, 55, 71, 439, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 4 x 55 x 71 x 439 x 17 = 12123494240
Therefore, the lowest common multiple of 416,440,284,878,442 is 12123494240.
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.
416 x 440 x 284 x 878 x 442 = 20173494415360
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.
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
284 : 1, 2, 4, 71, 142, 284
878 : 1, 2, 439, 878
442 : 1, 2, 13, 17, 26, 34, 221, 442
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 416,440,284,878,442, is 2.
Now, the common factors can be found like this.
416:2x 2x 2x 2x 2x 13
440:2x 2x 2x 5x 11
284:2x 2x 71
878:2x 439
442:2x 13x 17
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 2x 2x 2x 13 = 832
Therefore, the value for common factors is 832.
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 = 20173494415360/(2x832)
LCM = 20173494415360/1664
LCM = 12123494240
Thus, we can understand that the LCM of 416,440,284,878,442 is 12123494240.
