Find LCM of 379,177,428,856,861 with Prime Factorization
| 2 | 379, 177, 428, 856, 861 |
| 2 | 379, 177, 214, 428, 861 |
| 3 | 379, 177, 107, 214, 861 |
| 107 | 379, 59, 107, 214, 287 |
| 379, 59, 1, 2, 287 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 107 x 379 x 59 x 1 x 2 x 287 = 16480414776
Therefore, the lowest common multiple of 379,177,428,856,861 is 16480414776.
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.
379 x 177 x 428 x 856 x 861 = 21160852572384
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.
379 : 1, 379
177 : 1, 3, 59, 177
428 : 1, 2, 4, 107, 214, 428
856 : 1, 2, 4, 8, 107, 214, 428, 856
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 379,177,428,856,861, is 1.
Now, the common factors can be found like this.
379:379
177:3x 59
428:2x 2x 107
856:2x 2x 2x 107
861:3x 7x 41
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 3x 107 = 1284
Therefore, the value for common factors is 1284.
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 = 21160852572384/(1x1284)
LCM = 21160852572384/1284
LCM = 16480414776
Thus, we can understand that the LCM of 379,177,428,856,861 is 16480414776.
