Given numbers are 564,285,420,856
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 564,285,420,856 is 80262840.
Find LCM of 564,285,420,856 with Prime Factorization
| 2 | 564, 285, 420, 856 |
| 2 | 282, 285, 210, 428 |
| 3 | 141, 285, 105, 214 |
| 5 | 47, 95, 35, 214 |
| 47, 19, 7, 214 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 47 x 19 x 7 x 214 = 80262840
Therefore, the lowest common multiple of 564,285,420,856 is 80262840.
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.
564 x 285 x 420 x 856 = 57789244800
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.
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
285 : 1, 3, 5, 15, 19, 57, 95, 285
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 564,285,420,856, is 1.
Now, the common factors can be found like this.
564:2x 2x 3x 47
285:3x 5x 19
420:2x 2x 3x 5x 7
856:2x 2x 2x 107
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 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 57789244800/(1x720)
LCM = 57789244800/720
LCM = 80262840
Thus, we can understand that the LCM of 564,285,420,856 is 80262840.
