Given numbers are 681,330,123,738,837
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,330,123,738,837 is 856895490.
Find LCM of 681,330,123,738,837 with Prime Factorization
| 2 | 681, 330, 123, 738, 837 |
| 3 | 681, 165, 123, 369, 837 |
| 3 | 227, 55, 41, 123, 279 |
| 41 | 227, 55, 41, 41, 93 |
| 227, 55, 1, 1, 93 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 41 x 227 x 55 x 1 x 1 x 93 = 856895490
Therefore, the lowest common multiple of 681,330,123,738,837 is 856895490.
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.
681 x 330 x 123 x 738 x 837 = 17074499533740
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.
681 : 1, 3, 227, 681
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
123 : 1, 3, 41, 123
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
837 : 1, 3, 9, 27, 31, 93, 279, 837
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,330,123,738,837, is 3.
Now, the common factors can be found like this.
681:3x 227
330:2x 3x 5x 11
123:3x 41
738:2x 3x 3x 41
837:3x 3x 3x 31
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 3x 3x 41 = 6642
Therefore, the value for common factors is 6642.
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 = 17074499533740/(3x6642)
LCM = 17074499533740/19926
LCM = 856895490
Thus, we can understand that the LCM of 681,330,123,738,837 is 856895490.
