Given numbers are 181,638,704,924
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 181,638,704,924 is 77601216.
Find LCM of 181,638,704,924 with Prime Factorization
| 2 | 181, 638, 704, 924 |
| 2 | 181, 319, 352, 462 |
| 11 | 181, 319, 176, 231 |
| 181, 29, 16, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 181 x 29 x 16 x 21 = 77601216
Therefore, the lowest common multiple of 181,638,704,924 is 77601216.
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 638 x 704 x 924 = 75117977088
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
638 : 1, 2, 11, 22, 29, 58, 319, 638
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 181,638,704,924, is 1.
Now, the common factors can be found like this.
181:181
638:2x 11x 29
704:2x 2x 2x 2x 2x 2x 11
924:2x 2x 3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 11x 11 = 968
Therefore, the value for common factors is 968.
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 = 75117977088/(1x968)
LCM = 75117977088/968
LCM = 77601216
Thus, we can understand that the LCM of 181,638,704,924 is 77601216.
