The LCM of 763,312,858,823 is 2155120968.
Find LCM of 763,312,858,823 with Prime Factorization
| 2 | 763, 312, 858, 823 |
| 3 | 763, 156, 429, 823 |
| 13 | 763, 52, 143, 823 |
| 763, 4, 11, 823 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 763 x 4 x 11 x 823 = 2155120968
Therefore, the lowest common multiple of 763,312,858,823 is 2155120968.
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.
763 x 312 x 858 x 823 = 168099435504
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.
763 : 1, 7, 109, 763
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
823 : 1, 823
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 763,312,858,823, is 1.
Now, the common factors can be found like this.
763:7x 109
312:2x 2x 2x 3x 13
858:2x 3x 11x 13
823:823
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 13 = 78
Therefore, the value for common factors is 78.
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 = 168099435504/(1x78)
LCM = 168099435504/78
LCM = 2155120968
Thus, we can understand that the LCM of 763,312,858,823 is 2155120968.
