Find LCM of 181,861,742,159,776 with Prime Factorization
| 2 | 181, 861, 742, 159, 776 |
| 3 | 181, 861, 371, 159, 388 |
| 7 | 181, 287, 371, 53, 388 |
| 53 | 181, 41, 53, 53, 388 |
| 181, 41, 1, 1, 388 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 53 x 181 x 41 x 1 x 1 x 388 = 6409428648
Therefore, the lowest common multiple of 181,861,742,159,776 is 6409428648.
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 861 x 742 x 159 x 776 = 14267388170448
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
861 : 1, 3, 7, 21, 41, 123, 287, 861
742 : 1, 2, 7, 14, 53, 106, 371, 742
159 : 1, 3, 53, 159
776 : 1, 2, 4, 8, 97, 194, 388, 776
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 181,861,742,159,776, is 1.
Now, the common factors can be found like this.
181:181
861:3x 7x 41
742:2x 7x 53
159:3x 53
776:2x 2x 2x 97
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 7x 53 = 2226
Therefore, the value for common factors is 2226.
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 = 14267388170448/(1x2226)
LCM = 14267388170448/2226
LCM = 6409428648
Thus, we can understand that the LCM of 181,861,742,159,776 is 6409428648.
