Given numbers are 515,209,191,309
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,209,191,309 is 61674855.
Find LCM of 515,209,191,309 with Prime Factorization
| 103 | 515, 209, 191, 309 |
| 5, 209, 191, 3 |
Multiply the prime numbers at the bottom and the left side.
103 x 5 x 209 x 191 x 3 = 61674855
Therefore, the lowest common multiple of 515,209,191,309 is 61674855.
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.
515 x 209 x 191 x 309 = 6352510065
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.
515 : 1, 5, 103, 515
209 : 1, 11, 19, 209
191 : 1, 191
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,209,191,309, is 1.
Now, the common factors can be found like this.
515:5x 103
209:11x 19
191:191
309:3x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
103 = 103
Therefore, the value for common factors is 103.
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 = 6352510065/(1x103)
LCM = 6352510065/103
LCM = 61674855
Thus, we can understand that the LCM of 515,209,191,309 is 61674855.
