Given numbers are 442,847,731,509,209
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 442,847,731,509,209 is 155684551022.
Find LCM of 442,847,731,509,209 with Prime Factorization
| 11 | 442, 847, 731, 509, 209 |
| 17 | 442, 77, 731, 509, 19 |
| 26, 77, 43, 509, 19 |
Multiply the prime numbers at the bottom and the left side.
11 x 17 x 26 x 77 x 43 x 509 x 19 = 155684551022
Therefore, the lowest common multiple of 442,847,731,509,209 is 155684551022.
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.
442 x 847 x 731 x 509 x 209 = 29113011041114
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.
442 : 1, 2, 13, 17, 26, 34, 221, 442
847 : 1, 7, 11, 77, 121, 847
731 : 1, 17, 43, 731
509 : 1, 509
209 : 1, 11, 19, 209
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,847,731,509,209, is 1.
Now, the common factors can be found like this.
442:2x 13x 17
847:7x 11x 11
731:17x 43
509:509
209:11x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 17 = 187
Therefore, the value for common factors is 187.
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 = 29113011041114/(1x187)
LCM = 29113011041114/187
LCM = 155684551022
Thus, we can understand that the LCM of 442,847,731,509,209 is 155684551022.
