Given numbers are 209,145,955,809
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 209,145,955,809 is 4682698295.
Find LCM of 209,145,955,809 with Prime Factorization
| 5 | 209, 145, 955, 809 |
| 209, 29, 191, 809 |
Multiply the prime numbers at the bottom and the left side.
5 x 209 x 29 x 191 x 809 = 4682698295
Therefore, the lowest common multiple of 209,145,955,809 is 4682698295.
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.
209 x 145 x 955 x 809 = 23413491475
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.
209 : 1, 11, 19, 209
145 : 1, 5, 29, 145
955 : 1, 5, 191, 955
809 : 1, 809
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,145,955,809, is 1.
Now, the common factors can be found like this.
209:11x 19
145:5x 29
955:5x 191
809:809
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 23413491475/(1x5)
LCM = 23413491475/5
LCM = 4682698295
Thus, we can understand that the LCM of 209,145,955,809 is 4682698295.
