Given numbers are 904,790,115,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 904,790,115,638 is 2619895960.
Find LCM of 904,790,115,638 with Prime Factorization
| 2 | 904, 790, 115, 638 |
| 5 | 452, 395, 115, 319 |
| 452, 79, 23, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 452 x 79 x 23 x 319 = 2619895960
Therefore, the lowest common multiple of 904,790,115,638 is 2619895960.
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.
904 x 790 x 115 x 638 = 52397919200
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.
904 : 1, 2, 4, 8, 113, 226, 452, 904
790 : 1, 2, 5, 10, 79, 158, 395, 790
115 : 1, 5, 23, 115
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 904,790,115,638, is 1.
Now, the common factors can be found like this.
904:2x 2x 2x 113
790:2x 5x 79
115:5x 23
638:2x 11x 29
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 = 52397919200/(1x20)
LCM = 52397919200/20
LCM = 2619895960
Thus, we can understand that the LCM of 904,790,115,638 is 2619895960.
