Given numbers are 484,647,790,778,815
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 484,647,790,778,815 is 7843031218220.
Find LCM of 484,647,790,778,815 with Prime Factorization
| 2 | 484, 647, 790, 778, 815 |
| 5 | 242, 647, 395, 389, 815 |
| 242, 647, 79, 389, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 242 x 647 x 79 x 389 x 163 = 7843031218220
Therefore, the lowest common multiple of 484,647,790,778,815 is 7843031218220.
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.
484 x 647 x 790 x 778 x 815 = 156860624364400
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.
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
647 : 1, 647
790 : 1, 2, 5, 10, 79, 158, 395, 790
778 : 1, 2, 389, 778
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 484,647,790,778,815, is 1.
Now, the common factors can be found like this.
484:2x 2x 11x 11
647:647
790:2x 5x 79
778:2x 389
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.
2x 2x 5 = 20
Therefore, the value for common factors is 20.
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 = 156860624364400/(1x20)
LCM = 156860624364400/20
LCM = 7843031218220
Thus, we can understand that the LCM of 484,647,790,778,815 is 7843031218220.
