Given numbers are 454,727,940,919
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 454,727,940,919 is 142561951940.
Find LCM of 454,727,940,919 with Prime Factorization
| 2 | 454, 727, 940, 919 |
| 227, 727, 470, 919 |
Multiply the prime numbers at the bottom and the left side.
2 x 227 x 727 x 470 x 919 = 142561951940
Therefore, the lowest common multiple of 454,727,940,919 is 142561951940.
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.
454 x 727 x 940 x 919 = 285123903880
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.
454 : 1, 2, 227, 454
727 : 1, 727
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
919 : 1, 919
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 454,727,940,919, is 1.
Now, the common factors can be found like this.
454:2x 227
727:727
940:2x 2x 5x 47
919:919
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 285123903880/(1x2)
LCM = 285123903880/2
LCM = 142561951940
Thus, we can understand that the LCM of 454,727,940,919 is 142561951940.
