Given numbers are 649,231,581,664
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,231,581,664 is 9049656.
Find LCM of 649,231,581,664 with Prime Factorization
| 7 | 649, 231, 581, 664 |
| 11 | 649, 33, 83, 664 |
| 83 | 59, 3, 83, 664 |
| 59, 3, 1, 8 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 83 x 59 x 3 x 1 x 8 = 9049656
Therefore, the lowest common multiple of 649,231,581,664 is 9049656.
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.
649 x 231 x 581 x 664 = 57836351496
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.
649 : 1, 11, 59, 649
231 : 1, 3, 7, 11, 21, 33, 77, 231
581 : 1, 7, 83, 581
664 : 1, 2, 4, 8, 83, 166, 332, 664
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,231,581,664, is 1.
Now, the common factors can be found like this.
649:11x 59
231:3x 7x 11
581:7x 83
664:2x 2x 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.
7x 11x 83 = 6391
Therefore, the value for common factors is 6391.
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 = 57836351496/(1x6391)
LCM = 57836351496/6391
LCM = 9049656
Thus, we can understand that the LCM of 649,231,581,664 is 9049656.
