Given numbers are 717,822,644,951,209
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 717,822,644,951,209 is 4191130063428.
Find LCM of 717,822,644,951,209 with Prime Factorization
| 2 | 717, 822, 644, 951, 209 |
| 3 | 717, 411, 322, 951, 209 |
| 239, 137, 322, 317, 209 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 239 x 137 x 322 x 317 x 209 = 4191130063428
Therefore, the lowest common multiple of 717,822,644,951,209 is 4191130063428.
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.
717 x 822 x 644 x 951 x 209 = 75440341141704
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.
717 : 1, 3, 239, 717
822 : 1, 2, 3, 6, 137, 274, 411, 822
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
951 : 1, 3, 317, 951
209 : 1, 11, 19, 209
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,822,644,951,209, is 1.
Now, the common factors can be found like this.
717:3x 239
822:2x 3x 137
644:2x 2x 7x 23
951:3x 317
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.
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 = 75440341141704/(1x18)
LCM = 75440341141704/18
LCM = 4191130063428
Thus, we can understand that the LCM of 717,822,644,951,209 is 4191130063428.
