Given numbers are 181,454,961,778
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 181,454,961,778 is 30719024246.
Find LCM of 181,454,961,778 with Prime Factorization
| 2 | 181, 454, 961, 778 |
| 181, 227, 961, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 181 x 227 x 961 x 389 = 30719024246
Therefore, the lowest common multiple of 181,454,961,778 is 30719024246.
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 454 x 961 x 778 = 61438048492
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
454 : 1, 2, 227, 454
961 : 1, 31, 961
778 : 1, 2, 389, 778
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 181,454,961,778, is 1.
Now, the common factors can be found like this.
181:181
454:2x 227
961:31x 31
778:2x 389
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 61438048492/(1x2)
LCM = 61438048492/2
LCM = 30719024246
Thus, we can understand that the LCM of 181,454,961,778 is 30719024246.
