Given numbers are 655,865,458,801,815
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,865,458,801,815 is 6775993826010.
Find LCM of 655,865,458,801,815 with Prime Factorization
5 | 655, 865, 458, 801, 815 |
131, 173, 458, 801, 163 |
Multiply the prime numbers at the bottom and the left side.
5 x 131 x 173 x 458 x 801 x 163 = 6775993826010
Therefore, the lowest common multiple of 655,865,458,801,815 is 6775993826010.
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.
655 x 865 x 458 x 801 x 815 = 169399845650250
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.
655 : 1, 5, 131, 655
865 : 1, 5, 173, 865
458 : 1, 2, 229, 458
801 : 1, 3, 9, 89, 267, 801
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,865,458,801,815, is 1.
Now, the common factors can be found like this.
655:5x 131
865:5x 173
458:2x 229
801:3x 3x 89
815:5x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5 = 25
Therefore, the value for common factors is 25.
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 = 169399845650250/(1x25)
LCM = 169399845650250/25
LCM = 6775993826010
Thus, we can understand that the LCM of 655,865,458,801,815 is 6775993826010.
