Given numbers are 615,653,345,759
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,653,345,759 is 101603535.
Find LCM of 615,653,345,759 with Prime Factorization
| 3 | 615, 653, 345, 759 |
| 5 | 205, 653, 115, 253 |
| 23 | 41, 653, 23, 253 |
| 41, 653, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 23 x 41 x 653 x 1 x 11 = 101603535
Therefore, the lowest common multiple of 615,653,345,759 is 101603535.
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.
615 x 653 x 345 x 759 = 105159658725
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
653 : 1, 653
345 : 1, 3, 5, 15, 23, 69, 115, 345
759 : 1, 3, 11, 23, 33, 69, 253, 759
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,653,345,759, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
653:653
345:3x 5x 23
759:3x 11x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 23 = 1035
Therefore, the value for common factors is 1035.
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 = 105159658725/(1x1035)
LCM = 105159658725/1035
LCM = 101603535
Thus, we can understand that the LCM of 615,653,345,759 is 101603535.
