Given numbers are 813,945,963,763
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,945,963,763 is 2986835985.
Find LCM of 813,945,963,763 with Prime Factorization
| 3 | 813, 945, 963, 763 |
| 3 | 271, 315, 321, 763 |
| 7 | 271, 105, 107, 763 |
| 271, 15, 107, 109 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 271 x 15 x 107 x 109 = 2986835985
Therefore, the lowest common multiple of 813,945,963,763 is 2986835985.
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.
813 x 945 x 963 x 763 = 564512001165
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.
813 : 1, 3, 271, 813
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
963 : 1, 3, 9, 107, 321, 963
763 : 1, 7, 109, 763
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,945,963,763, is 1.
Now, the common factors can be found like this.
813:3x 271
945:3x 3x 3x 5x 7
963:3x 3x 107
763:7x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 7 = 189
Therefore, the value for common factors is 189.
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 = 564512001165/(1x189)
LCM = 564512001165/189
LCM = 2986835985
Thus, we can understand that the LCM of 813,945,963,763 is 2986835985.
