Given numbers are 520,856,871,992
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 520,856,871,992 is 462257120.
Find LCM of 520,856,871,992 with Prime Factorization
| 2 | 520, 856, 871, 992 |
| 2 | 260, 428, 871, 496 |
| 2 | 130, 214, 871, 248 |
| 13 | 65, 107, 871, 124 |
| 5, 107, 67, 124 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 5 x 107 x 67 x 124 = 462257120
Therefore, the lowest common multiple of 520,856,871,992 is 462257120.
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.
520 x 856 x 871 x 992 = 384597923840
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.
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
856 : 1, 2, 4, 8, 107, 214, 428, 856
871 : 1, 13, 67, 871
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,856,871,992, is 1.
Now, the common factors can be found like this.
520:2x 2x 2x 5x 13
856:2x 2x 2x 107
871:13x 67
992:2x 2x 2x 2x 2x 31
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 2x 2x 13 = 832
Therefore, the value for common factors is 832.
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 = 384597923840/(1x832)
LCM = 384597923840/832
LCM = 462257120
Thus, we can understand that the LCM of 520,856,871,992 is 462257120.
