Given numbers are 215,789,345,762,209
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 215,789,345,762,209 is 207120603030.
Find LCM of 215,789,345,762,209 with Prime Factorization
| 3 | 215, 789, 345, 762, 209 |
| 5 | 215, 263, 115, 254, 209 |
| 43, 263, 23, 254, 209 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 43 x 263 x 23 x 254 x 209 = 207120603030
Therefore, the lowest common multiple of 215,789,345,762,209 is 207120603030.
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.
215 x 789 x 345 x 762 x 209 = 9320427136350
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.
215 : 1, 5, 43, 215
789 : 1, 3, 263, 789
345 : 1, 3, 5, 15, 23, 69, 115, 345
762 : 1, 2, 3, 6, 127, 254, 381, 762
209 : 1, 11, 19, 209
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,789,345,762,209, is 1.
Now, the common factors can be found like this.
215:5x 43
789:3x 263
345:3x 5x 23
762:2x 3x 127
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.
3x 3x 5 = 45
Therefore, the value for common factors is 45.
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 = 9320427136350/(1x45)
LCM = 9320427136350/45
LCM = 207120603030
Thus, we can understand that the LCM of 215,789,345,762,209 is 207120603030.
