Find LCM of 930,768,891,143,765 with Prime Factorization
| 2 | 930, 768, 891, 143, 765 |
| 3 | 465, 384, 891, 143, 765 |
| 3 | 155, 128, 297, 143, 255 |
| 5 | 155, 128, 99, 143, 85 |
| 11 | 31, 128, 99, 143, 17 |
| 31, 128, 9, 13, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 31 x 128 x 9 x 13 x 17 = 7813428480
Therefore, the lowest common multiple of 930,768,891,143,765 is 7813428480.
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.
930 x 768 x 891 x 143 x 765 = 69617647756800
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.
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
143 : 1, 11, 13, 143
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 930,768,891,143,765, is 1.
Now, the common factors can be found like this.
930:2x 3x 5x 31
768:2x 2x 2x 2x 2x 2x 2x 2x 3
891:3x 3x 3x 3x 11
143:11x 13
765:3x 3x 5x 17
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 3x 3x 5x 11 = 8910
Therefore, the value for common factors is 8910.
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 = 69617647756800/(1x8910)
LCM = 69617647756800/8910
LCM = 7813428480
Thus, we can understand that the LCM of 930,768,891,143,765 is 7813428480.
