Given numbers are 515,905,307,102,476
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,905,307,102,476 is 40865083140.
Find LCM of 515,905,307,102,476 with Prime Factorization
| 2 | 515, 905, 307, 102, 476 |
| 5 | 515, 905, 307, 51, 238 |
| 17 | 103, 181, 307, 51, 238 |
| 103, 181, 307, 3, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 103 x 181 x 307 x 3 x 14 = 40865083140
Therefore, the lowest common multiple of 515,905,307,102,476 is 40865083140.
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 905 x 307 x 102 x 476 = 6947064133800
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
905 : 1, 5, 181, 905
307 : 1, 307
102 : 1, 2, 3, 6, 17, 34, 51, 102
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,905,307,102,476, is 1.
Now, the common factors can be found like this.
515:5x 103
905:5x 181
307:307
102:2x 3x 17
476:2x 2x 7x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 17 = 170
Therefore, the value for common factors is 170.
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 = 6947064133800/(1x170)
LCM = 6947064133800/170
LCM = 40865083140
Thus, we can understand that the LCM of 515,905,307,102,476 is 40865083140.
