Given numbers are 515,687,310,672,847
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,687,310,672,847 is 297275452320.
Find LCM of 515,687,310,672,847 with Prime Factorization
| 2 | 515, 687, 310, 672, 847 |
| 3 | 515, 687, 155, 336, 847 |
| 5 | 515, 229, 155, 112, 847 |
| 7 | 103, 229, 31, 112, 847 |
| 103, 229, 31, 16, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 103 x 229 x 31 x 16 x 121 = 297275452320
Therefore, the lowest common multiple of 515,687,310,672,847 is 297275452320.
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 687 x 310 x 672 x 847 = 62427844987200
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
687 : 1, 3, 229, 687
310 : 1, 2, 5, 10, 31, 62, 155, 310
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,687,310,672,847, is 1.
Now, the common factors can be found like this.
515:5x 103
687:3x 229
310:2x 5x 31
672:2x 2x 2x 2x 2x 3x 7
847:7x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 62427844987200/(1x210)
LCM = 62427844987200/210
LCM = 297275452320
Thus, we can understand that the LCM of 515,687,310,672,847 is 297275452320.
