Given numbers are 648,489,690,410,865
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 648,489,690,410,865 is 86156968680.
Find LCM of 648,489,690,410,865 with Prime Factorization
| 2 | 648, 489, 690, 410, 865 |
| 3 | 324, 489, 345, 205, 865 |
| 5 | 108, 163, 115, 205, 865 |
| 108, 163, 23, 41, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 108 x 163 x 23 x 41 x 173 = 86156968680
Therefore, the lowest common multiple of 648,489,690,410,865 is 86156968680.
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.
648 x 489 x 690 x 410 x 865 = 77541271812000
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.
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
489 : 1, 3, 163, 489
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
410 : 1, 2, 5, 10, 41, 82, 205, 410
865 : 1, 5, 173, 865
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,489,690,410,865, is 1.
Now, the common factors can be found like this.
648:2x 2x 2x 3x 3x 3x 3
489:3x 163
690:2x 3x 5x 23
410:2x 5x 41
865:5x 173
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 3x 3x 5x 5 = 900
Therefore, the value for common factors is 900.
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 = 77541271812000/(1x900)
LCM = 77541271812000/900
LCM = 86156968680
Thus, we can understand that the LCM of 648,489,690,410,865 is 86156968680.
