Given numbers are 191,477,171,107
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 191,477,171,107 is 185220531.
Find LCM of 191,477,171,107 with Prime Factorization
| 3 | 191, 477, 171, 107 |
| 3 | 191, 159, 57, 107 |
| 191, 53, 19, 107 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 191 x 53 x 19 x 107 = 185220531
Therefore, the lowest common multiple of 191,477,171,107 is 185220531.
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.
191 x 477 x 171 x 107 = 1666984779
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.
191 : 1, 191
477 : 1, 3, 9, 53, 159, 477
171 : 1, 3, 9, 19, 57, 171
107 : 1, 107
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,477,171,107, is 1.
Now, the common factors can be found like this.
191:191
477:3x 3x 53
171:3x 3x 19
107:107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 1666984779/(1x9)
LCM = 1666984779/9
LCM = 185220531
Thus, we can understand that the LCM of 191,477,171,107 is 185220531.
