Given numbers are 515,647,246,855,629
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,647,246,855,629 is 2938814120790.
Find LCM of 515,647,246,855,629 with Prime Factorization
| 3 | 515, 647, 246, 855, 629 |
| 5 | 515, 647, 82, 285, 629 |
| 103, 647, 82, 57, 629 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 103 x 647 x 82 x 57 x 629 = 2938814120790
Therefore, the lowest common multiple of 515,647,246,855,629 is 2938814120790.
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.
515 x 647 x 246 x 855 x 629 = 44082211811850
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.
515 : 1, 5, 103, 515
647 : 1, 647
246 : 1, 2, 3, 6, 41, 82, 123, 246
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
629 : 1, 17, 37, 629
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,647,246,855,629, is 1.
Now, the common factors can be found like this.
515:5x 103
647:647
246:2x 3x 41
855:3x 3x 5x 19
629:17x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 44082211811850/(1x15)
LCM = 44082211811850/15
LCM = 2938814120790
Thus, we can understand that the LCM of 515,647,246,855,629 is 2938814120790.
