Given numbers are 793,285,615,574
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 793,285,615,574 is 129726870.
Find LCM of 793,285,615,574 with Prime Factorization
| 3 | 793, 285, 615, 574 |
| 5 | 793, 95, 205, 574 |
| 41 | 793, 19, 41, 574 |
| 793, 19, 1, 14 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 41 x 793 x 19 x 1 x 14 = 129726870
Therefore, the lowest common multiple of 793,285,615,574 is 129726870.
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.
793 x 285 x 615 x 574 = 79782025050
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.
793 : 1, 13, 61, 793
285 : 1, 3, 5, 15, 19, 57, 95, 285
615 : 1, 3, 5, 15, 41, 123, 205, 615
574 : 1, 2, 7, 14, 41, 82, 287, 574
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 793,285,615,574, is 1.
Now, the common factors can be found like this.
793:13x 61
285:3x 5x 19
615:3x 5x 41
574:2x 7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 41 = 615
Therefore, the value for common factors is 615.
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 = 79782025050/(1x615)
LCM = 79782025050/615
LCM = 129726870
Thus, we can understand that the LCM of 793,285,615,574 is 129726870.
