Given numbers are 855,246,570,645,899
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,246,570,645,899 is 2710242270.
Find LCM of 855,246,570,645,899 with Prime Factorization
| 2 | 855, 246, 570, 645, 899 |
| 3 | 855, 123, 285, 645, 899 |
| 5 | 95, 41, 285, 215, 899 |
| 19 | 19, 41, 57, 43, 899 |
| 1, 41, 3, 43, 899 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 1 x 41 x 3 x 43 x 899 = 2710242270
Therefore, the lowest common multiple of 855,246,570,645,899 is 2710242270.
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.
855 x 246 x 570 x 645 x 899 = 69517714225500
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
246 : 1, 2, 3, 6, 41, 82, 123, 246
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
645 : 1, 3, 5, 15, 43, 129, 215, 645
899 : 1, 29, 31, 899
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,246,570,645,899, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
246:2x 3x 41
570:2x 3x 5x 19
645:3x 5x 43
899:29x 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 3x 3x 3x 5x 5x 19 = 25650
Therefore, the value for common factors is 25650.
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 = 69517714225500/(1x25650)
LCM = 69517714225500/25650
LCM = 2710242270
Thus, we can understand that the LCM of 855,246,570,645,899 is 2710242270.
