Given numbers are 351,867,154,495
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 351,867,154,495 is 78108030.
Find LCM of 351,867,154,495 with Prime Factorization
| 3 | 351, 867, 154, 495 |
| 3 | 117, 289, 154, 165 |
| 11 | 39, 289, 154, 55 |
| 39, 289, 14, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 39 x 289 x 14 x 5 = 78108030
Therefore, the lowest common multiple of 351,867,154,495 is 78108030.
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.
351 x 867 x 154 x 495 = 23198084910
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.
351 : 1, 3, 9, 13, 27, 39, 117, 351
867 : 1, 3, 17, 51, 289, 867
154 : 1, 2, 7, 11, 14, 22, 77, 154
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 351,867,154,495, is 1.
Now, the common factors can be found like this.
351:3x 3x 3x 13
867:3x 17x 17
154:2x 7x 11
495:3x 3x 5x 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 11 = 297
Therefore, the value for common factors is 297.
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 = 23198084910/(1x297)
LCM = 23198084910/297
LCM = 78108030
Thus, we can understand that the LCM of 351,867,154,495 is 78108030.
