Find LCM of 291,745,891,891 with Prime Factorization
| 3 | 291, 745, 891, 891 |
| 3 | 97, 745, 297, 297 |
| 3 | 97, 745, 99, 99 |
| 3 | 97, 745, 33, 33 |
| 11 | 97, 745, 11, 11 |
| 97, 745, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 3 x 11 x 97 x 745 x 1 x 1 = 64388115
Therefore, the lowest common multiple of 291,745,891,891 is 64388115.
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.
291 x 745 x 891 x 891 = 172109431395
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.
291 : 1, 3, 97, 291
745 : 1, 5, 149, 745
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,745,891,891, is 1.
Now, the common factors can be found like this.
291:3x 97
745:5x 149
891:3x 3x 3x 3x 11
891:3x 3x 3x 3x 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 11 = 2673
Therefore, the value for common factors is 2673.
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 = 172109431395/(1x2673)
LCM = 172109431395/2673
LCM = 64388115
Thus, we can understand that the LCM of 291,745,891,891 is 64388115.
