Given numbers are 205,671,399,854
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 205,671,399,854 is 109768890.
Find LCM of 205,671,399,854 with Prime Factorization
| 7 | 205, 671, 399, 854 |
| 61 | 205, 671, 57, 122 |
| 205, 11, 57, 2 |
Multiply the prime numbers at the bottom and the left side.
7 x 61 x 205 x 11 x 57 x 2 = 109768890
Therefore, the lowest common multiple of 205,671,399,854 is 109768890.
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.
205 x 671 x 399 x 854 = 46871316030
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.
205 : 1, 5, 41, 205
671 : 1, 11, 61, 671
399 : 1, 3, 7, 19, 21, 57, 133, 399
854 : 1, 2, 7, 14, 61, 122, 427, 854
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 205,671,399,854, is 1.
Now, the common factors can be found like this.
205:5x 41
671:11x 61
399:3x 7x 19
854:2x 7x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 61 = 427
Therefore, the value for common factors is 427.
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 = 46871316030/(1x427)
LCM = 46871316030/427
LCM = 109768890
Thus, we can understand that the LCM of 205,671,399,854 is 109768890.
