Given numbers are 805,526,428,856
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 805,526,428,856 is 181228040.
Find LCM of 805,526,428,856 with Prime Factorization
| 2 | 805, 526, 428, 856 |
| 2 | 805, 263, 214, 428 |
| 107 | 805, 263, 107, 214 |
| 805, 263, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 107 x 805 x 263 x 1 x 2 = 181228040
Therefore, the lowest common multiple of 805,526,428,856 is 181228040.
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.
805 x 526 x 428 x 856 = 155131202240
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
526 : 1, 2, 263, 526
428 : 1, 2, 4, 107, 214, 428
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,526,428,856, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
526:2x 263
428:2x 2x 107
856:2x 2x 2x 107
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 107 = 856
Therefore, the value for common factors is 856.
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 = 155131202240/(1x856)
LCM = 155131202240/856
LCM = 181228040
Thus, we can understand that the LCM of 805,526,428,856 is 181228040.
