Given numbers are 504,860,476,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 504,860,476,561 is 20263320.
Find LCM of 504,860,476,561 with Prime Factorization
| 2 | 504, 860, 476, 561 |
| 2 | 252, 430, 238, 561 |
| 3 | 126, 215, 119, 561 |
| 7 | 42, 215, 119, 187 |
| 17 | 6, 215, 17, 187 |
| 6, 215, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 17 x 6 x 215 x 1 x 11 = 20263320
Therefore, the lowest common multiple of 504,860,476,561 is 20263320.
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.
504 x 860 x 476 x 561 = 115744083840
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.
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 504,860,476,561, is 1.
Now, the common factors can be found like this.
504:2x 2x 2x 3x 3x 7
860:2x 2x 5x 43
476:2x 2x 7x 17
561:3x 11x 17
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 3x 7x 17 = 5712
Therefore, the value for common factors is 5712.
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 = 115744083840/(1x5712)
LCM = 115744083840/5712
LCM = 20263320
Thus, we can understand that the LCM of 504,860,476,561 is 20263320.
