Given numbers are 423,400,856,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 423,400,856,871 is 15768932400.
Find LCM of 423,400,856,871 with Prime Factorization
| 2 | 423, 400, 856, 871 |
| 2 | 423, 200, 428, 871 |
| 2 | 423, 100, 214, 871 |
| 423, 50, 107, 871 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 423 x 50 x 107 x 871 = 15768932400
Therefore, the lowest common multiple of 423,400,856,871 is 15768932400.
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.
423 x 400 x 856 x 871 = 126151459200
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.
423 : 1, 3, 9, 47, 141, 423
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
856 : 1, 2, 4, 8, 107, 214, 428, 856
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,400,856,871, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
400:2x 2x 2x 2x 5x 5
856:2x 2x 2x 107
871:13x 67
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 2 = 8
Therefore, the value for common factors is 8.
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 = 126151459200/(1x8)
LCM = 126151459200/8
LCM = 15768932400
Thus, we can understand that the LCM of 423,400,856,871 is 15768932400.
