Given numbers are 291,638,184,405,738
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 291,638,184,405,738 is 94540766760.
Find LCM of 291,638,184,405,738 with Prime Factorization
| 2 | 291, 638, 184, 405, 738 |
| 3 | 291, 319, 92, 405, 369 |
| 3 | 97, 319, 92, 135, 123 |
| 97, 319, 92, 45, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 97 x 319 x 92 x 45 x 41 = 94540766760
Therefore, the lowest common multiple of 291,638,184,405,738 is 94540766760.
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 638 x 184 x 405 x 738 = 10210402810080
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
638 : 1, 2, 11, 22, 29, 58, 319, 638
184 : 1, 2, 4, 8, 23, 46, 92, 184
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,638,184,405,738, is 1.
Now, the common factors can be found like this.
291:3x 97
638:2x 11x 29
184:2x 2x 2x 23
405:3x 3x 3x 3x 5
738:2x 3x 3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 10210402810080/(1x108)
LCM = 10210402810080/108
LCM = 94540766760
Thus, we can understand that the LCM of 291,638,184,405,738 is 94540766760.
