Given numbers are 678,728,832,568
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 678,728,832,568 is 140177856.
Find LCM of 678,728,832,568 with Prime Factorization
| 2 | 678, 728, 832, 568 |
| 2 | 339, 364, 416, 284 |
| 2 | 339, 182, 208, 142 |
| 13 | 339, 91, 104, 71 |
| 339, 7, 8, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 339 x 7 x 8 x 71 = 140177856
Therefore, the lowest common multiple of 678,728,832,568 is 140177856.
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.
678 x 728 x 832 x 568 = 233255952384
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
568 : 1, 2, 4, 8, 71, 142, 284, 568
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,728,832,568, is 2.
Now, the common factors can be found like this.
678:2x 3x 113
728:2x 2x 2x 7x 13
832:2x 2x 2x 2x 2x 2x 13
568:2x 2x 2x 71
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 13 = 832
Therefore, the value for common factors is 832.
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 = 233255952384/(2x832)
LCM = 233255952384/1664
LCM = 140177856
Thus, we can understand that the LCM of 678,728,832,568 is 140177856.
