Given numbers are 391,253,705,184
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,253,705,184 is 24257640.
Find LCM of 391,253,705,184 with Prime Factorization
| 23 | 391, 253, 705, 184 |
| 17, 11, 705, 8 |
Multiply the prime numbers at the bottom and the left side.
23 x 17 x 11 x 705 x 8 = 24257640
Therefore, the lowest common multiple of 391,253,705,184 is 24257640.
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.
391 x 253 x 705 x 184 = 12832291560
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.
391 : 1, 17, 23, 391
253 : 1, 11, 23, 253
705 : 1, 3, 5, 15, 47, 141, 235, 705
184 : 1, 2, 4, 8, 23, 46, 92, 184
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,253,705,184, is 1.
Now, the common factors can be found like this.
391:17x 23
253:11x 23
705:3x 5x 47
184:2x 2x 2x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 23 = 529
Therefore, the value for common factors is 529.
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 = 12832291560/(1x529)
LCM = 12832291560/529
LCM = 24257640
Thus, we can understand that the LCM of 391,253,705,184 is 24257640.
