Given numbers are 764,818,663,206,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 764,818,663,206,494 is 405434797716.
Find LCM of 764,818,663,206,494 with Prime Factorization
| 2 | 764, 818, 663, 206, 494 |
| 13 | 382, 409, 663, 103, 247 |
| 382, 409, 51, 103, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 382 x 409 x 51 x 103 x 19 = 405434797716
Therefore, the lowest common multiple of 764,818,663,206,494 is 405434797716.
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.
764 x 818 x 663 x 206 x 494 = 42165218962464
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.
764 : 1, 2, 4, 191, 382, 764
818 : 1, 2, 409, 818
663 : 1, 3, 13, 17, 39, 51, 221, 663
206 : 1, 2, 103, 206
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 764,818,663,206,494, is 1.
Now, the common factors can be found like this.
764:2x 2x 191
818:2x 409
663:3x 13x 17
206:2x 103
494:2x 13x 19
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 13 = 104
Therefore, the value for common factors is 104.
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 = 42165218962464/(1x104)
LCM = 42165218962464/104
LCM = 405434797716
Thus, we can understand that the LCM of 764,818,663,206,494 is 405434797716.
