Given numbers are 434,117,861,726,979
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 434,117,861,726,979 is 22419959562.
Find LCM of 434,117,861,726,979 with Prime Factorization
| 2 | 434, 117, 861, 726, 979 |
| 3 | 217, 117, 861, 363, 979 |
| 7 | 217, 39, 287, 121, 979 |
| 11 | 31, 39, 41, 121, 979 |
| 31, 39, 41, 11, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 31 x 39 x 41 x 11 x 89 = 22419959562
Therefore, the lowest common multiple of 434,117,861,726,979 is 22419959562.
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.
434 x 117 x 861 x 726 x 979 = 31074063952932
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.
434 : 1, 2, 7, 14, 31, 62, 217, 434
117 : 1, 3, 9, 13, 39, 117
861 : 1, 3, 7, 21, 41, 123, 287, 861
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
979 : 1, 11, 89, 979
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 434,117,861,726,979, is 1.
Now, the common factors can be found like this.
434:2x 7x 31
117:3x 3x 13
861:3x 7x 41
726:2x 3x 11x 11
979:11x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7x 11 = 1386
Therefore, the value for common factors is 1386.
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 = 31074063952932/(1x1386)
LCM = 31074063952932/1386
LCM = 22419959562
Thus, we can understand that the LCM of 434,117,861,726,979 is 22419959562.
