Given numbers are 861,858,677,137
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,858,677,137 is 22839070254.
Find LCM of 861,858,677,137 with Prime Factorization
3 | 861, 858, 677, 137 |
287, 286, 677, 137 |
Multiply the prime numbers at the bottom and the left side.
3 x 287 x 286 x 677 x 137 = 22839070254
Therefore, the lowest common multiple of 861,858,677,137 is 22839070254.
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.
861 x 858 x 677 x 137 = 68517210762
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
677 : 1, 677
137 : 1, 137
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,858,677,137, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
858:2x 3x 11x 13
677:677
137:137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 68517210762/(1x3)
LCM = 68517210762/3
LCM = 22839070254
Thus, we can understand that the LCM of 861,858,677,137 is 22839070254.
