Given numbers are 663,809,957,155,449
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 663,809,957,155,449 is 11907779175435.
Find LCM of 663,809,957,155,449 with Prime Factorization
| 3 | 663, 809, 957, 155, 449 |
| 221, 809, 319, 155, 449 |
Multiply the prime numbers at the bottom and the left side.
3 x 221 x 809 x 319 x 155 x 449 = 11907779175435
Therefore, the lowest common multiple of 663,809,957,155,449 is 11907779175435.
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.
663 x 809 x 957 x 155 x 449 = 35723337526305
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.
663 : 1, 3, 13, 17, 39, 51, 221, 663
809 : 1, 809
957 : 1, 3, 11, 29, 33, 87, 319, 957
155 : 1, 5, 31, 155
449 : 1, 449
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,809,957,155,449, is 1.
Now, the common factors can be found like this.
663:3x 13x 17
809:809
957:3x 11x 29
155:5x 31
449:449
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 35723337526305/(1x3)
LCM = 35723337526305/3
LCM = 11907779175435
Thus, we can understand that the LCM of 663,809,957,155,449 is 11907779175435.
