Given numbers are 515,253,208,345
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,253,208,345 is 81304080.
Find LCM of 515,253,208,345 with Prime Factorization
| 5 | 515, 253, 208, 345 |
| 23 | 103, 253, 208, 69 |
| 103, 11, 208, 3 |
Multiply the prime numbers at the bottom and the left side.
5 x 23 x 103 x 11 x 208 x 3 = 81304080
Therefore, the lowest common multiple of 515,253,208,345 is 81304080.
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 253 x 208 x 345 = 9349969200
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
253 : 1, 11, 23, 253
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
345 : 1, 3, 5, 15, 23, 69, 115, 345
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,253,208,345, is 1.
Now, the common factors can be found like this.
515:5x 103
253:11x 23
208:2x 2x 2x 2x 13
345:3x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 23 = 115
Therefore, the value for common factors is 115.
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 = 9349969200/(1x115)
LCM = 9349969200/115
LCM = 81304080
Thus, we can understand that the LCM of 515,253,208,345 is 81304080.
