Given numbers are 646,606,738,913,166
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,606,738,913,166 is 21981181662.
Find LCM of 646,606,738,913,166 with Prime Factorization
| 2 | 646, 606, 738, 913, 166 |
| 3 | 323, 303, 369, 913, 83 |
| 83 | 323, 101, 123, 913, 83 |
| 323, 101, 123, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 83 x 323 x 101 x 123 x 11 x 1 = 21981181662
Therefore, the lowest common multiple of 646,606,738,913,166 is 21981181662.
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.
646 x 606 x 738 x 913 x 166 = 43786513870704
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
606 : 1, 2, 3, 6, 101, 202, 303, 606
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
913 : 1, 11, 83, 913
166 : 1, 2, 83, 166
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,606,738,913,166, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
606:2x 3x 101
738:2x 3x 3x 41
913:11x 83
166:2x 83
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 2x 3x 83 = 1992
Therefore, the value for common factors is 1992.
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 = 43786513870704/(1x1992)
LCM = 43786513870704/1992
LCM = 21981181662
Thus, we can understand that the LCM of 646,606,738,913,166 is 21981181662.
