Given numbers are 489,491,920,806,651
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,491,920,806,651 is 623133736680.
Find LCM of 489,491,920,806,651 with Prime Factorization
2 | 489, 491, 920, 806, 651 |
3 | 489, 491, 460, 403, 651 |
31 | 163, 491, 460, 403, 217 |
163, 491, 460, 13, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 31 x 163 x 491 x 460 x 13 x 7 = 623133736680
Therefore, the lowest common multiple of 489,491,920,806,651 is 623133736680.
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.
489 x 491 x 920 x 806 x 651 = 115902875022480
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.
489 : 1, 3, 163, 489
491 : 1, 491
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
806 : 1, 2, 13, 26, 31, 62, 403, 806
651 : 1, 3, 7, 21, 31, 93, 217, 651
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,491,920,806,651, is 1.
Now, the common factors can be found like this.
489:3x 163
491:491
920:2x 2x 2x 5x 23
806:2x 13x 31
651:3x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 31 = 186
Therefore, the value for common factors is 186.
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 = 115902875022480/(1x186)
LCM = 115902875022480/186
LCM = 623133736680
Thus, we can understand that the LCM of 489,491,920,806,651 is 623133736680.
