Find LCM of 418,616,943,456,678 with Prime Factorization
| 2 | 418, 616, 943, 456, 678 |
| 2 | 209, 308, 943, 228, 339 |
| 2 | 209, 154, 943, 114, 339 |
| 3 | 209, 77, 943, 57, 339 |
| 11 | 209, 77, 943, 19, 113 |
| 19 | 19, 7, 943, 19, 113 |
| 1, 7, 943, 1, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 19 x 1 x 7 x 943 x 1 x 113 = 3741499608
Therefore, the lowest common multiple of 418,616,943,456,678 is 3741499608.
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.
418 x 616 x 943 x 456 x 678 = 75069448134912
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
943 : 1, 23, 41, 943
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
678 : 1, 2, 3, 6, 113, 226, 339, 678
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,616,943,456,678, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
616:2x 2x 2x 7x 11
943:23x 41
456:2x 2x 2x 3x 19
678:2x 3x 113
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 3x 11x 19 = 20064
Therefore, the value for common factors is 20064.
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 = 75069448134912/(1x20064)
LCM = 75069448134912/20064
LCM = 3741499608
Thus, we can understand that the LCM of 418,616,943,456,678 is 3741499608.
