Given numbers are 154,753,423,251
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 154,753,423,251 is 16350642.
Find LCM of 154,753,423,251 with Prime Factorization
| 3 | 154, 753, 423, 251 |
| 251 | 154, 251, 141, 251 |
| 154, 1, 141, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 251 x 154 x 1 x 141 x 1 = 16350642
Therefore, the lowest common multiple of 154,753,423,251 is 16350642.
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 753 x 423 x 251 = 12312033426
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
753 : 1, 3, 251, 753
423 : 1, 3, 9, 47, 141, 423
251 : 1, 251
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,753,423,251, is 1.
Now, the common factors can be found like this.
154:2x 7x 11
753:3x 251
423:3x 3x 47
251:251
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 251 = 753
Therefore, the value for common factors is 753.
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 = 12312033426/(1x753)
LCM = 12312033426/753
LCM = 16350642
Thus, we can understand that the LCM of 154,753,423,251 is 16350642.
