Given numbers are 191,990,440,464
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 191,990,440,464 is 43868880.
Find LCM of 191,990,440,464 with Prime Factorization
| 2 | 191, 990, 440, 464 |
| 2 | 191, 495, 220, 232 |
| 2 | 191, 495, 110, 116 |
| 5 | 191, 495, 55, 58 |
| 11 | 191, 99, 11, 58 |
| 191, 9, 1, 58 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 11 x 191 x 9 x 1 x 58 = 43868880
Therefore, the lowest common multiple of 191,990,440,464 is 43868880.
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 990 x 440 x 464 = 38604614400
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
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,990,440,464, is 1.
Now, the common factors can be found like this.
191:191
990:2x 3x 3x 5x 11
440:2x 2x 2x 5x 11
464:2x 2x 2x 2x 29
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 2x 5x 11 = 880
Therefore, the value for common factors is 880.
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 = 38604614400/(1x880)
LCM = 38604614400/880
LCM = 43868880
Thus, we can understand that the LCM of 191,990,440,464 is 43868880.
