Given numbers are 858,646,902,616
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 858,646,902,616 is 318149832.
Find LCM of 858,646,902,616 with Prime Factorization
| 2 | 858, 646, 902, 616 |
| 11 | 429, 323, 451, 308 |
| 39, 323, 41, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 39 x 323 x 41 x 28 = 318149832
Therefore, the lowest common multiple of 858,646,902,616 is 318149832.
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.
858 x 646 x 902 x 616 = 307969037376
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
646 : 1, 2, 17, 19, 34, 38, 323, 646
902 : 1, 2, 11, 22, 41, 82, 451, 902
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,646,902,616, is 2.
Now, the common factors can be found like this.
858:2x 3x 11x 13
646:2x 17x 19
902:2x 11x 41
616:2x 2x 2x 7x 11
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 11x 11 = 484
Therefore, the value for common factors is 484.
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 = 307969037376/(2x484)
LCM = 307969037376/968
LCM = 318149832
Thus, we can understand that the LCM of 858,646,902,616 is 318149832.
