Given numbers are 654,486,411,867,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 654,486,411,867,861 is 601953680034.
Find LCM of 654,486,411,867,861 with Prime Factorization
2 | 654, 486, 411, 867, 861 |
3 | 327, 243, 411, 867, 861 |
109, 81, 137, 289, 287 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 109 x 81 x 137 x 289 x 287 = 601953680034
Therefore, the lowest common multiple of 654,486,411,867,861 is 601953680034.
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.
654 x 486 x 411 x 867 x 861 = 97516496165508
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.
654 : 1, 2, 3, 6, 109, 218, 327, 654
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
411 : 1, 3, 137, 411
867 : 1, 3, 17, 51, 289, 867
861 : 1, 3, 7, 21, 41, 123, 287, 861
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,486,411,867,861, is 3.
Now, the common factors can be found like this.
654:2x 3x 109
486:2x 3x 3x 3x 3x 3
411:3x 137
867:3x 17x 17
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 3x 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 97516496165508/(3x54)
LCM = 97516496165508/162
LCM = 601953680034
Thus, we can understand that the LCM of 654,486,411,867,861 is 601953680034.
