Find LCM of 458,512,798,656,861 with Prime Factorization
| 2 | 458, 512, 798, 656, 861 |
| 2 | 229, 256, 399, 328, 861 |
| 2 | 229, 128, 399, 164, 861 |
| 2 | 229, 64, 399, 82, 861 |
| 3 | 229, 32, 399, 41, 861 |
| 7 | 229, 32, 133, 41, 287 |
| 41 | 229, 32, 19, 41, 41 |
| 229, 32, 19, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 41 x 229 x 32 x 19 x 1 x 1 = 1918060032
Therefore, the lowest common multiple of 458,512,798,656,861 is 1918060032.
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.
458 x 512 x 798 x 656 x 861 = 105692780003328
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.
458 : 1, 2, 229, 458
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 458,512,798,656,861, is 1.
Now, the common factors can be found like this.
458:2x 229
512:2x 2x 2x 2x 2x 2x 2x 2x 2
798:2x 3x 7x 19
656:2x 2x 2x 2x 41
861:3x 7x 41
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 3x 7x 41 = 55104
Therefore, the value for common factors is 55104.
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 = 105692780003328/(1x55104)
LCM = 105692780003328/55104
LCM = 1918060032
Thus, we can understand that the LCM of 458,512,798,656,861 is 1918060032.
