Given numbers are 904,135,840,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 904,135,840,782 is 334023480.
Find LCM of 904,135,840,782 with Prime Factorization
| 2 | 904, 135, 840, 782 |
| 2 | 452, 135, 420, 391 |
| 2 | 226, 135, 210, 391 |
| 3 | 113, 135, 105, 391 |
| 5 | 113, 45, 35, 391 |
| 113, 9, 7, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 113 x 9 x 7 x 391 = 334023480
Therefore, the lowest common multiple of 904,135,840,782 is 334023480.
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 135 x 840 x 782 = 80165635200
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
135 : 1, 3, 5, 9, 15, 27, 45, 135
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 904,135,840,782, is 1.
Now, the common factors can be found like this.
904:2x 2x 2x 113
135:3x 3x 3x 5
840:2x 2x 2x 3x 5x 7
782:2x 17x 23
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 2x 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 80165635200/(1x240)
LCM = 80165635200/240
LCM = 334023480
Thus, we can understand that the LCM of 904,135,840,782 is 334023480.
