Given numbers are 242,643,979,668,509
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 242,643,979,668,509 is 2354401873604.
Find LCM of 242,643,979,668,509 with Prime Factorization
| 2 | 242, 643, 979, 668, 509 |
| 11 | 121, 643, 979, 334, 509 |
| 11, 643, 89, 334, 509 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 11 x 643 x 89 x 334 x 509 = 2354401873604
Therefore, the lowest common multiple of 242,643,979,668,509 is 2354401873604.
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.
242 x 643 x 979 x 668 x 509 = 51796841219288
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.
242 : 1, 2, 11, 22, 121, 242
643 : 1, 643
979 : 1, 11, 89, 979
668 : 1, 2, 4, 167, 334, 668
509 : 1, 509
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,643,979,668,509, is 1.
Now, the common factors can be found like this.
242:2x 11x 11
643:643
979:11x 89
668:2x 2x 167
509:509
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 51796841219288/(1x22)
LCM = 51796841219288/22
LCM = 2354401873604
Thus, we can understand that the LCM of 242,643,979,668,509 is 2354401873604.
