Given numbers are 546,538,208,898,946
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 546,538,208,898,946 is 249541275984.
Find LCM of 546,538,208,898,946 with Prime Factorization
| 2 | 546, 538, 208, 898, 946 |
| 13 | 273, 269, 104, 449, 473 |
| 21, 269, 8, 449, 473 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 21 x 269 x 8 x 449 x 473 = 249541275984
Therefore, the lowest common multiple of 546,538,208,898,946 is 249541275984.
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.
546 x 538 x 208 x 898 x 946 = 51904585404672
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.
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
538 : 1, 2, 269, 538
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
898 : 1, 2, 449, 898
946 : 1, 2, 11, 22, 43, 86, 473, 946
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 546,538,208,898,946, is 2.
Now, the common factors can be found like this.
546:2x 3x 7x 13
538:2x 269
208:2x 2x 2x 2x 13
898:2x 449
946:2x 11x 43
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 13 = 104
Therefore, the value for common factors is 104.
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 = 51904585404672/(2x104)
LCM = 51904585404672/208
LCM = 249541275984
Thus, we can understand that the LCM of 546,538,208,898,946 is 249541275984.
