Find LCM of 416,920,786,897 with Prime Factorization
| 2 | 416, 920, 786, 897 |
| 2 | 208, 460, 393, 897 |
| 2 | 104, 230, 393, 897 |
| 3 | 52, 115, 393, 897 |
| 13 | 52, 115, 131, 299 |
| 23 | 4, 115, 131, 23 |
| 4, 5, 131, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 23 x 4 x 5 x 131 x 1 = 18801120
Therefore, the lowest common multiple of 416,920,786,897 is 18801120.
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 920 x 786 x 897 = 269833674240
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
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
786 : 1, 2, 3, 6, 131, 262, 393, 786
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 416,920,786,897, is 1.
Now, the common factors can be found like this.
416:2x 2x 2x 2x 2x 13
920:2x 2x 2x 5x 23
786:2x 3x 131
897:3x 13x 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 2x 3x 13x 23 = 14352
Therefore, the value for common factors is 14352.
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 = 269833674240/(1x14352)
LCM = 269833674240/14352
LCM = 18801120
Thus, we can understand that the LCM of 416,920,786,897 is 18801120.
