Given numbers are 881,956,665,561,920
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 881,956,665,561,920 is 14453603573640.
Find LCM of 881,956,665,561,920 with Prime Factorization
| 2 | 881, 956, 665, 561, 920 |
| 2 | 881, 478, 665, 561, 460 |
| 5 | 881, 239, 665, 561, 230 |
| 881, 239, 133, 561, 46 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 881 x 239 x 133 x 561 x 46 = 14453603573640
Therefore, the lowest common multiple of 881,956,665,561,920 is 14453603573640.
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.
881 x 956 x 665 x 561 x 920 = 289072071472800
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.
881 : 1, 881
956 : 1, 2, 4, 239, 478, 956
665 : 1, 5, 7, 19, 35, 95, 133, 665
561 : 1, 3, 11, 17, 33, 51, 187, 561
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 881,956,665,561,920, is 1.
Now, the common factors can be found like this.
881:881
956:2x 2x 239
665:5x 7x 19
561:3x 11x 17
920:2x 2x 2x 5x 23
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 5 = 20
Therefore, the value for common factors is 20.
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 = 289072071472800/(1x20)
LCM = 289072071472800/20
LCM = 14453603573640
Thus, we can understand that the LCM of 881,956,665,561,920 is 14453603573640.
