Given numbers are 685,658,793,104,830
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 685,658,793,104,830 is 118666391480.
Find LCM of 685,658,793,104,830 with Prime Factorization
| 2 | 685, 658, 793, 104, 830 |
| 5 | 685, 329, 793, 52, 415 |
| 13 | 137, 329, 793, 52, 83 |
| 137, 329, 61, 4, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 137 x 329 x 61 x 4 x 83 = 118666391480
Therefore, the lowest common multiple of 685,658,793,104,830 is 118666391480.
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.
685 x 658 x 793 x 104 x 830 = 30853261784800
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.
685 : 1, 5, 137, 685
658 : 1, 2, 7, 14, 47, 94, 329, 658
793 : 1, 13, 61, 793
104 : 1, 2, 4, 8, 13, 26, 52, 104
830 : 1, 2, 5, 10, 83, 166, 415, 830
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,658,793,104,830, is 1.
Now, the common factors can be found like this.
685:5x 137
658:2x 7x 47
793:13x 61
104:2x 2x 2x 13
830:2x 5x 83
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 5x 13 = 260
Therefore, the value for common factors is 260.
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 = 30853261784800/(1x260)
LCM = 30853261784800/260
LCM = 118666391480
Thus, we can understand that the LCM of 685,658,793,104,830 is 118666391480.
