Find LCM of 181,194,285,905,441 with Prime Factorization
| 3 | 181, 194, 285, 905, 441 |
| 5 | 181, 194, 95, 905, 147 |
| 181 | 181, 194, 19, 181, 147 |
| 1, 194, 19, 1, 147 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 181 x 1 x 194 x 19 x 1 x 147 = 1471101030
Therefore, the lowest common multiple of 181,194,285,905,441 is 1471101030.
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 194 x 285 x 905 x 441 = 3994039296450
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
194 : 1, 2, 97, 194
285 : 1, 3, 5, 15, 19, 57, 95, 285
905 : 1, 5, 181, 905
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 181,194,285,905,441, is 1.
Now, the common factors can be found like this.
181:181
194:2x 97
285:3x 5x 19
905:5x 181
441:3x 3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 181 = 2715
Therefore, the value for common factors is 2715.
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 = 3994039296450/(1x2715)
LCM = 3994039296450/2715
LCM = 1471101030
Thus, we can understand that the LCM of 181,194,285,905,441 is 1471101030.
