Find LCM of 765,891,305,423,363 with Prime Factorization
| 3 | 765, 891, 305, 423, 363 |
| 3 | 255, 297, 305, 141, 121 |
| 5 | 85, 99, 305, 47, 121 |
| 11 | 17, 99, 61, 47, 121 |
| 17, 9, 61, 47, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 11 x 17 x 9 x 61 x 47 x 11 = 2388454695
Therefore, the lowest common multiple of 765,891,305,423,363 is 2388454695.
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.
765 x 891 x 305 x 423 x 363 = 31921696998675
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
305 : 1, 5, 61, 305
423 : 1, 3, 9, 47, 141, 423
363 : 1, 3, 11, 33, 121, 363
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,891,305,423,363, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
891:3x 3x 3x 3x 11
305:5x 61
423:3x 3x 47
363:3x 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.
3x 3x 3x 3x 3x 5x 11 = 13365
Therefore, the value for common factors is 13365.
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 = 31921696998675/(1x13365)
LCM = 31921696998675/13365
LCM = 2388454695
Thus, we can understand that the LCM of 765,891,305,423,363 is 2388454695.
