Given numbers are 836,678,380,976
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 836,678,380,976 is 345752880.
Find LCM of 836,678,380,976 with Prime Factorization
| 2 | 836, 678, 380, 976 |
| 2 | 418, 339, 190, 488 |
| 19 | 209, 339, 95, 244 |
| 11, 339, 5, 244 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 11 x 339 x 5 x 244 = 345752880
Therefore, the lowest common multiple of 836,678,380,976 is 345752880.
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.
836 x 678 x 380 x 976 = 210217751040
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.
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
678 : 1, 2, 3, 6, 113, 226, 339, 678
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,678,380,976, is 2.
Now, the common factors can be found like this.
836:2x 2x 11x 19
678:2x 3x 113
380:2x 2x 5x 19
976:2x 2x 2x 2x 61
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 19 = 304
Therefore, the value for common factors is 304.
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 = 210217751040/(2x304)
LCM = 210217751040/608
LCM = 345752880
Thus, we can understand that the LCM of 836,678,380,976 is 345752880.
