Given numbers are 868,854,853,449,898
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 868,854,853,449,898 is 20278925156.
Find LCM of 868,854,853,449,898 with Prime Factorization
| 2 | 868, 854, 853, 449, 898 |
| 7 | 434, 427, 853, 449, 449 |
| 449 | 62, 61, 853, 449, 449 |
| 62, 61, 853, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 449 x 62 x 61 x 853 x 1 x 1 = 20278925156
Therefore, the lowest common multiple of 868,854,853,449,898 is 20278925156.
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.
868 x 854 x 853 x 449 x 898 = 254946647061232
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.
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
854 : 1, 2, 7, 14, 61, 122, 427, 854
853 : 1, 853
449 : 1, 449
898 : 1, 2, 449, 898
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,854,853,449,898, is 1.
Now, the common factors can be found like this.
868:2x 2x 7x 31
854:2x 7x 61
853:853
449:449
898:2x 449
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 7x 449 = 12572
Therefore, the value for common factors is 12572.
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 = 254946647061232/(1x12572)
LCM = 254946647061232/12572
LCM = 20278925156
Thus, we can understand that the LCM of 868,854,853,449,898 is 20278925156.
