Find LCM of 154,891,964,963,991 with Prime Factorization
| 2 | 154, 891, 964, 963, 991 |
| 3 | 77, 891, 482, 963, 991 |
| 3 | 77, 297, 482, 321, 991 |
| 11 | 77, 99, 482, 107, 991 |
| 7, 9, 482, 107, 991 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 7 x 9 x 482 x 107 x 991 = 637544069316
Therefore, the lowest common multiple of 154,891,964,963,991 is 637544069316.
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.
154 x 891 x 964 x 963 x 991 = 126233725724568
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.
154 : 1, 2, 7, 11, 14, 22, 77, 154
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
964 : 1, 2, 4, 241, 482, 964
963 : 1, 3, 9, 107, 321, 963
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,891,964,963,991, is 1.
Now, the common factors can be found like this.
154:2x 7x 11
891:3x 3x 3x 3x 11
964:2x 2x 241
963:3x 3x 107
991:991
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 11 = 198
Therefore, the value for common factors is 198.
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 = 126233725724568/(1x198)
LCM = 126233725724568/198
LCM = 637544069316
Thus, we can understand that the LCM of 154,891,964,963,991 is 637544069316.
