Find LCM of 891,869,552,790 with Prime Factorization
| 2 | 891, 869, 552, 790 |
| 3 | 891, 869, 276, 395 |
| 11 | 297, 869, 92, 395 |
| 79 | 27, 79, 92, 395 |
| 27, 1, 92, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 79 x 27 x 1 x 92 x 5 = 64757880
Therefore, the lowest common multiple of 891,869,552,790 is 64757880.
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.
891 x 869 x 552 x 790 = 337647586320
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
869 : 1, 11, 79, 869
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
790 : 1, 2, 5, 10, 79, 158, 395, 790
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,869,552,790, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
869:11x 79
552:2x 2x 2x 3x 23
790:2x 5x 79
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 11x 79 = 5214
Therefore, the value for common factors is 5214.
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 = 337647586320/(1x5214)
LCM = 337647586320/5214
LCM = 64757880
Thus, we can understand that the LCM of 891,869,552,790 is 64757880.
