The LCM of 275,816,105,639,315 is 334580400.
Find LCM of 275,816,105,639,315 with Prime Factorization
| 3 | 275, 816, 105, 639, 315 |
| 3 | 275, 272, 35, 213, 105 |
| 5 | 275, 272, 35, 71, 35 |
| 7 | 55, 272, 7, 71, 7 |
| 55, 272, 1, 71, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 55 x 272 x 1 x 71 x 1 = 334580400
Therefore, the lowest common multiple of 275,816,105,639,315 is 334580400.
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.
275 x 816 x 105 x 639 x 315 = 4742677170000
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.
275 : 1, 5, 11, 25, 55, 275
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
105 : 1, 3, 5, 7, 15, 21, 35, 105
639 : 1, 3, 9, 71, 213, 639
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 275,816,105,639,315, is 1.
Now, the common factors can be found like this.
275:5x 5x 11
816:2x 2x 2x 2x 3x 17
105:3x 5x 7
639:3x 3x 71
315:3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 5x 5x 7 = 14175
Therefore, the value for common factors is 14175.
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 = 4742677170000/(1x14175)
LCM = 4742677170000/14175
LCM = 334580400
Thus, we can understand that the LCM of 275,816,105,639,315 is 334580400.
