Given numbers are 836,191,691,678,816
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 836,191,691,678,816 is 2543468146032.
Find LCM of 836,191,691,678,816 with Prime Factorization
| 2 | 836, 191, 691, 678, 816 |
| 2 | 418, 191, 691, 339, 408 |
| 3 | 209, 191, 691, 339, 204 |
| 209, 191, 691, 113, 68 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 209 x 191 x 691 x 113 x 68 = 2543468146032
Therefore, the lowest common multiple of 836,191,691,678,816 is 2543468146032.
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 191 x 691 x 678 x 816 = 61043235504768
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
191 : 1, 191
691 : 1, 691
678 : 1, 2, 3, 6, 113, 226, 339, 678
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,191,691,678,816, is 1.
Now, the common factors can be found like this.
836:2x 2x 11x 19
191:191
691:691
678:2x 3x 113
816:2x 2x 2x 2x 3x 17
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 3 = 24
Therefore, the value for common factors is 24.
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 = 61043235504768/(1x24)
LCM = 61043235504768/24
LCM = 2543468146032
Thus, we can understand that the LCM of 836,191,691,678,816 is 2543468146032.
