Find LCM of 864,758,909,856 with Prime Factorization
| 2 | 864, 758, 909, 856 |
| 2 | 432, 379, 909, 428 |
| 2 | 216, 379, 909, 214 |
| 3 | 108, 379, 909, 107 |
| 3 | 36, 379, 303, 107 |
| 12, 379, 101, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 12 x 379 x 101 x 107 = 3538816992
Therefore, the lowest common multiple of 864,758,909,856 is 3538816992.
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.
864 x 758 x 909 x 856 = 509589646848
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.
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
758 : 1, 2, 379, 758
909 : 1, 3, 9, 101, 303, 909
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,758,909,856, is 1.
Now, the common factors can be found like this.
864:2x 2x 2x 2x 2x 3x 3x 3
758:2x 379
909:3x 3x 101
856:2x 2x 2x 107
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 3 = 144
Therefore, the value for common factors is 144.
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 = 509589646848/(1x144)
LCM = 509589646848/144
LCM = 3538816992
Thus, we can understand that the LCM of 864,758,909,856 is 3538816992.
