Given numbers are 663,117,647,507,869
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 663,117,647,507,869 is 14537917251.
Find LCM of 663,117,647,507,869 with Prime Factorization
| 3 | 663, 117, 647, 507, 869 |
| 13 | 221, 39, 647, 169, 869 |
| 17, 3, 647, 13, 869 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 17 x 3 x 647 x 13 x 869 = 14537917251
Therefore, the lowest common multiple of 663,117,647,507,869 is 14537917251.
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 117 x 647 x 507 x 869 = 22112172138771
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
117 : 1, 3, 9, 13, 39, 117
647 : 1, 647
507 : 1, 3, 13, 39, 169, 507
869 : 1, 11, 79, 869
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,117,647,507,869, is 1.
Now, the common factors can be found like this.
663:3x 13x 17
117:3x 3x 13
647:647
507:3x 13x 13
869:11x 79
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 13x 13 = 1521
Therefore, the value for common factors is 1521.
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 = 22112172138771/(1x1521)
LCM = 22112172138771/1521
LCM = 14537917251
Thus, we can understand that the LCM of 663,117,647,507,869 is 14537917251.
