Given numbers are 586,686,444,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 586,686,444,561 is 8344230972.
Find LCM of 586,686,444,561 with Prime Factorization
| 2 | 586, 686, 444, 561 |
| 3 | 293, 343, 222, 561 |
| 293, 343, 74, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 293 x 343 x 74 x 187 = 8344230972
Therefore, the lowest common multiple of 586,686,444,561 is 8344230972.
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.
586 x 686 x 444 x 561 = 100130771664
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.
586 : 1, 2, 293, 586
686 : 1, 2, 7, 14, 49, 98, 343, 686
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 586,686,444,561, is 1.
Now, the common factors can be found like this.
586:2x 293
686:2x 7x 7x 7
444:2x 2x 3x 37
561:3x 11x 17
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 3 = 12
Therefore, the value for common factors is 12.
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 = 100130771664/(1x12)
LCM = 100130771664/12
LCM = 8344230972
Thus, we can understand that the LCM of 586,686,444,561 is 8344230972.
