Find LCM of 861,356,429,826,428 with Prime Factorization
| 2 | 861, 356, 429, 826, 428 |
| 2 | 861, 178, 429, 413, 214 |
| 3 | 861, 89, 429, 413, 107 |
| 7 | 287, 89, 143, 413, 107 |
| 41, 89, 143, 59, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 41 x 89 x 143 x 59 x 107 = 276710077644
Therefore, the lowest common multiple of 861,356,429,826,428 is 276710077644.
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.
861 x 356 x 429 x 826 x 428 = 46487293044192
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
356 : 1, 2, 4, 89, 178, 356
429 : 1, 3, 11, 13, 33, 39, 143, 429
826 : 1, 2, 7, 14, 59, 118, 413, 826
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,356,429,826,428, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
356:2x 2x 89
429:3x 11x 13
826:2x 7x 59
428:2x 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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 46487293044192/(1x168)
LCM = 46487293044192/168
LCM = 276710077644
Thus, we can understand that the LCM of 861,356,429,826,428 is 276710077644.
