Given numbers are 479,640,686,574,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 479,640,686,574,489 is 2108153953920.
Find LCM of 479,640,686,574,489 with Prime Factorization
| 2 | 479, 640, 686, 574, 489 |
| 7 | 479, 320, 343, 287, 489 |
| 479, 320, 49, 41, 489 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 479 x 320 x 49 x 41 x 489 = 2108153953920
Therefore, the lowest common multiple of 479,640,686,574,489 is 2108153953920.
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.
479 x 640 x 686 x 574 x 489 = 59028310709760
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.
479 : 1, 479
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
686 : 1, 2, 7, 14, 49, 98, 343, 686
574 : 1, 2, 7, 14, 41, 82, 287, 574
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 479,640,686,574,489, is 1.
Now, the common factors can be found like this.
479:479
640:2x 2x 2x 2x 2x 2x 2x 5
686:2x 7x 7x 7
574:2x 7x 41
489:3x 163
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 7 = 28
Therefore, the value for common factors is 28.
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 = 59028310709760/(1x28)
LCM = 59028310709760/28
LCM = 2108153953920
Thus, we can understand that the LCM of 479,640,686,574,489 is 2108153953920.
