Given numbers are 129,999,947,880,643
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 129,999,947,880,643 is 23018529069360.
Find LCM of 129,999,947,880,643 with Prime Factorization
| 3 | 129, 999, 947, 880, 643 |
| 43, 333, 947, 880, 643 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 333 x 947 x 880 x 643 = 23018529069360
Therefore, the lowest common multiple of 129,999,947,880,643 is 23018529069360.
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.
129 x 999 x 947 x 880 x 643 = 69055587208080
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.
129 : 1, 3, 43, 129
999 : 1, 3, 9, 27, 37, 111, 333, 999
947 : 1, 947
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 129,999,947,880,643, is 1.
Now, the common factors can be found like this.
129:3x 43
999:3x 3x 3x 37
947:947
880:2x 2x 2x 2x 5x 11
643:643
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 = 69055587208080/(1x3)
LCM = 69055587208080/3
LCM = 23018529069360
Thus, we can understand that the LCM of 129,999,947,880,643 is 23018529069360.
