Find LCM of 387,390,195,878,751 with Prime Factorization
| 2 | 387, 390, 195, 878, 751 |
| 3 | 387, 195, 195, 439, 751 |
| 5 | 129, 65, 65, 439, 751 |
| 13 | 129, 13, 13, 439, 751 |
| 129, 1, 1, 439, 751 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 129 x 1 x 1 x 439 x 751 = 16586653590
Therefore, the lowest common multiple of 387,390,195,878,751 is 16586653590.
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.
387 x 390 x 195 x 878 x 751 = 19406384700300
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.
387 : 1, 3, 9, 43, 129, 387
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
195 : 1, 3, 5, 13, 15, 39, 65, 195
878 : 1, 2, 439, 878
751 : 1, 751
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,390,195,878,751, is 1.
Now, the common factors can be found like this.
387:3x 3x 43
390:2x 3x 5x 13
195:3x 5x 13
878:2x 439
751:751
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 3x 5x 13 = 1170
Therefore, the value for common factors is 1170.
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 = 19406384700300/(1x1170)
LCM = 19406384700300/1170
LCM = 16586653590
Thus, we can understand that the LCM of 387,390,195,878,751 is 16586653590.
