Given numbers are 923,454,440,429
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 923,454,440,429 is 276567720.
Find LCM of 923,454,440,429 with Prime Factorization
| 2 | 923, 454, 440, 429 |
| 11 | 923, 227, 220, 429 |
| 13 | 923, 227, 20, 39 |
| 71, 227, 20, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 71 x 227 x 20 x 3 = 276567720
Therefore, the lowest common multiple of 923,454,440,429 is 276567720.
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.
923 x 454 x 440 x 429 = 79098367920
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.
923 : 1, 13, 71, 923
454 : 1, 2, 227, 454
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
429 : 1, 3, 11, 13, 33, 39, 143, 429
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,454,440,429, is 1.
Now, the common factors can be found like this.
923:13x 71
454:2x 227
440:2x 2x 2x 5x 11
429:3x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 13 = 286
Therefore, the value for common factors is 286.
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 = 79098367920/(1x286)
LCM = 79098367920/286
LCM = 276567720
Thus, we can understand that the LCM of 923,454,440,429 is 276567720.
