Given numbers are 856,826,160,546
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 856,826,160,546 is 275751840.
Find LCM of 856,826,160,546 with Prime Factorization
| 2 | 856, 826, 160, 546 |
| 2 | 428, 413, 80, 273 |
| 2 | 214, 413, 40, 273 |
| 7 | 107, 413, 20, 273 |
| 107, 59, 20, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 107 x 59 x 20 x 39 = 275751840
Therefore, the lowest common multiple of 856,826,160,546 is 275751840.
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 826 x 160 x 546 = 61768412160
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
826 : 1, 2, 7, 14, 59, 118, 413, 826
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,826,160,546, is 2.
Now, the common factors can be found like this.
856:2x 2x 2x 107
826:2x 7x 59
160:2x 2x 2x 2x 2x 5
546:2x 3x 7x 13
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 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 61768412160/(2x112)
LCM = 61768412160/224
LCM = 275751840
Thus, we can understand that the LCM of 856,826,160,546 is 275751840.
