Given numbers are 858,694,355,716,284
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 858,694,355,716,284 is 37837997340.
Find LCM of 858,694,355,716,284 with Prime Factorization
| 2 | 858, 694, 355, 716, 284 |
| 2 | 429, 347, 355, 358, 142 |
| 71 | 429, 347, 355, 179, 71 |
| 429, 347, 5, 179, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 71 x 429 x 347 x 5 x 179 x 1 = 37837997340
Therefore, the lowest common multiple of 858,694,355,716,284 is 37837997340.
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.
858 x 694 x 355 x 716 x 284 = 42983964978240
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
694 : 1, 2, 347, 694
355 : 1, 5, 71, 355
716 : 1, 2, 4, 179, 358, 716
284 : 1, 2, 4, 71, 142, 284
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,694,355,716,284, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
694:2x 347
355:5x 71
716:2x 2x 179
284:2x 2x 71
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 71 = 1136
Therefore, the value for common factors is 1136.
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 = 42983964978240/(1x1136)
LCM = 42983964978240/1136
LCM = 37837997340
Thus, we can understand that the LCM of 858,694,355,716,284 is 37837997340.
