Given numbers are 864,606,646,686,908
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 864,606,646,686,908 is 2194611324192.
Find LCM of 864,606,646,686,908 with Prime Factorization
| 2 | 864, 606, 646, 686, 908 |
| 2 | 432, 303, 323, 343, 454 |
| 3 | 216, 303, 323, 343, 227 |
| 72, 101, 323, 343, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 72 x 101 x 323 x 343 x 227 = 2194611324192
Therefore, the lowest common multiple of 864,606,646,686,908 is 2194611324192.
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 606 x 646 x 686 x 908 = 210682687122432
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
606 : 1, 2, 3, 6, 101, 202, 303, 606
646 : 1, 2, 17, 19, 34, 38, 323, 646
686 : 1, 2, 7, 14, 49, 98, 343, 686
908 : 1, 2, 4, 227, 454, 908
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,606,646,686,908, is 2.
Now, the common factors can be found like this.
864:2x 2x 2x 2x 2x 3x 3x 3
606:2x 3x 101
646:2x 17x 19
686:2x 7x 7x 7
908:2x 2x 227
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 3 = 48
Therefore, the value for common factors is 48.
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 = 210682687122432/(2x48)
LCM = 210682687122432/96
LCM = 2194611324192
Thus, we can understand that the LCM of 864,606,646,686,908 is 2194611324192.
