Given numbers are 130,643,969,789,432
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 130,643,969,789,432 is 1533791572560.
Find LCM of 130,643,969,789,432 with Prime Factorization
| 2 | 130, 643, 969, 789, 432 |
| 3 | 65, 643, 969, 789, 216 |
| 65, 643, 323, 263, 72 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 65 x 643 x 323 x 263 x 72 = 1533791572560
Therefore, the lowest common multiple of 130,643,969,789,432 is 1533791572560.
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.
130 x 643 x 969 x 789 x 432 = 27608248306080
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.
130 : 1, 2, 5, 10, 13, 26, 65, 130
643 : 1, 643
969 : 1, 3, 17, 19, 51, 57, 323, 969
789 : 1, 3, 263, 789
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,643,969,789,432, is 1.
Now, the common factors can be found like this.
130:2x 5x 13
643:643
969:3x 17x 19
789:3x 263
432:2x 2x 2x 2x 3x 3x 3
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 3 = 18
Therefore, the value for common factors is 18.
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 = 27608248306080/(1x18)
LCM = 27608248306080/18
LCM = 1533791572560
Thus, we can understand that the LCM of 130,643,969,789,432 is 1533791572560.
