Given numbers are 181,561,847,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 181,561,847,638 is 453482106.
Find LCM of 181,561,847,638 with Prime Factorization
11 | 181, 561, 847, 638 |
181, 51, 77, 58 |
Multiply the prime numbers at the bottom and the left side.
11 x 181 x 51 x 77 x 58 = 453482106
Therefore, the lowest common multiple of 181,561,847,638 is 453482106.
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.
181 x 561 x 847 x 638 = 54871334826
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.
181 : 1, 181
561 : 1, 3, 11, 17, 33, 51, 187, 561
847 : 1, 7, 11, 77, 121, 847
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 181,561,847,638, is 1.
Now, the common factors can be found like this.
181:181
561:3x 11x 17
847:7x 11x 11
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11 = 121
Therefore, the value for common factors is 121.
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 = 54871334826/(1x121)
LCM = 54871334826/121
LCM = 453482106
Thus, we can understand that the LCM of 181,561,847,638 is 453482106.
