Find LCM of 387,721,207,595,545 with Prime Factorization
| 3 | 387, 721, 207, 595, 545 |
| 3 | 129, 721, 69, 595, 545 |
| 5 | 43, 721, 23, 595, 545 |
| 7 | 43, 721, 23, 119, 109 |
| 43, 103, 23, 17, 109 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 43 x 103 x 23 x 17 x 109 = 59459258565
Therefore, the lowest common multiple of 387,721,207,595,545 is 59459258565.
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 721 x 207 x 595 x 545 = 18729666447975
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
721 : 1, 7, 103, 721
207 : 1, 3, 9, 23, 69, 207
595 : 1, 5, 7, 17, 35, 85, 119, 595
545 : 1, 5, 109, 545
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,721,207,595,545, is 1.
Now, the common factors can be found like this.
387:3x 3x 43
721:7x 103
207:3x 3x 23
595:5x 7x 17
545:5x 109
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 5x 7 = 315
Therefore, the value for common factors is 315.
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 = 18729666447975/(1x315)
LCM = 18729666447975/315
LCM = 59459258565
Thus, we can understand that the LCM of 387,721,207,595,545 is 59459258565.
