Given numbers are 195,489,553,305,857
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 195,489,553,305,857 is 918878318085.
Find LCM of 195,489,553,305,857 with Prime Factorization
| 3 | 195, 489, 553, 305, 857 |
| 5 | 65, 163, 553, 305, 857 |
| 13, 163, 553, 61, 857 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 163 x 553 x 61 x 857 = 918878318085
Therefore, the lowest common multiple of 195,489,553,305,857 is 918878318085.
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.
195 x 489 x 553 x 305 x 857 = 13783174771275
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.
195 : 1, 3, 5, 13, 15, 39, 65, 195
489 : 1, 3, 163, 489
553 : 1, 7, 79, 553
305 : 1, 5, 61, 305
857 : 1, 857
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 195,489,553,305,857, is 1.
Now, the common factors can be found like this.
195:3x 5x 13
489:3x 163
553:7x 79
305:5x 61
857:857
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 13783174771275/(1x15)
LCM = 13783174771275/15
LCM = 918878318085
Thus, we can understand that the LCM of 195,489,553,305,857 is 918878318085.
