Given numbers are 856,814,777,647,813
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 856,814,777,647,813 is 1282806170184.
Find LCM of 856,814,777,647,813 with Prime Factorization
| 2 | 856, 814, 777, 647, 813 |
| 3 | 428, 407, 777, 647, 813 |
| 37 | 428, 407, 259, 647, 271 |
| 428, 11, 7, 647, 271 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 37 x 428 x 11 x 7 x 647 x 271 = 1282806170184
Therefore, the lowest common multiple of 856,814,777,647,813 is 1282806170184.
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.
856 x 814 x 777 x 647 x 813 = 284782969780848
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.
856 : 1, 2, 4, 8, 107, 214, 428, 856
814 : 1, 2, 11, 22, 37, 74, 407, 814
777 : 1, 3, 7, 21, 37, 111, 259, 777
647 : 1, 647
813 : 1, 3, 271, 813
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,814,777,647,813, is 1.
Now, the common factors can be found like this.
856:2x 2x 2x 107
814:2x 11x 37
777:3x 7x 37
647:647
813:3x 271
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 37 = 222
Therefore, the value for common factors is 222.
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 = 284782969780848/(1x222)
LCM = 284782969780848/222
LCM = 1282806170184
Thus, we can understand that the LCM of 856,814,777,647,813 is 1282806170184.
