Given numbers are 396,790,836,756
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,790,836,756 is 62411580.
Find LCM of 396,790,836,756 with Prime Factorization
| 2 | 396, 790, 836, 756 |
| 2 | 198, 395, 418, 378 |
| 3 | 99, 395, 209, 189 |
| 3 | 33, 395, 209, 63 |
| 11 | 11, 395, 209, 21 |
| 1, 395, 19, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 1 x 395 x 19 x 21 = 62411580
Therefore, the lowest common multiple of 396,790,836,756 is 62411580.
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.
396 x 790 x 836 x 756 = 197719885440
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.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
790 : 1, 2, 5, 10, 79, 158, 395, 790
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,790,836,756, is 2.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
790:2x 5x 79
836:2x 2x 11x 19
756:2x 2x 3x 3x 3x 7
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 3x 11 = 1584
Therefore, the value for common factors is 1584.
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 = 197719885440/(2x1584)
LCM = 197719885440/3168
LCM = 62411580
Thus, we can understand that the LCM of 396,790,836,756 is 62411580.
