Given numbers are 766,405,846,637
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 766,405,846,637 is 9287975970.
Find LCM of 766,405,846,637 with Prime Factorization
| 2 | 766, 405, 846, 637 |
| 3 | 383, 405, 423, 637 |
| 3 | 383, 135, 141, 637 |
| 383, 45, 47, 637 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 383 x 45 x 47 x 637 = 9287975970
Therefore, the lowest common multiple of 766,405,846,637 is 9287975970.
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.
766 x 405 x 846 x 637 = 167183567460
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.
766 : 1, 2, 383, 766
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
637 : 1, 7, 13, 49, 91, 637
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 766,405,846,637, is 1.
Now, the common factors can be found like this.
766:2x 383
405:3x 3x 3x 3x 5
846:2x 3x 3x 47
637:7x 7x 13
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 3 = 18
Therefore, the value for common factors is 18.
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 = 167183567460/(1x18)
LCM = 167183567460/18
LCM = 9287975970
Thus, we can understand that the LCM of 766,405,846,637 is 9287975970.
