Given numbers are 398,471,694,546,208
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,471,694,546,208 is 47354890128.
Find LCM of 398,471,694,546,208 with Prime Factorization
| 2 | 398, 471, 694, 546, 208 |
| 3 | 199, 471, 347, 273, 104 |
| 13 | 199, 157, 347, 91, 104 |
| 199, 157, 347, 7, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 199 x 157 x 347 x 7 x 8 = 47354890128
Therefore, the lowest common multiple of 398,471,694,546,208 is 47354890128.
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.
398 x 471 x 694 x 546 x 208 = 14774725719936
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.
398 : 1, 2, 199, 398
471 : 1, 3, 157, 471
694 : 1, 2, 347, 694
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,471,694,546,208, is 1.
Now, the common factors can be found like this.
398:2x 199
471:3x 157
694:2x 347
546:2x 3x 7x 13
208:2x 2x 2x 2x 13
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 3x 13 = 312
Therefore, the value for common factors is 312.
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 = 14774725719936/(1x312)
LCM = 14774725719936/312
LCM = 47354890128
Thus, we can understand that the LCM of 398,471,694,546,208 is 47354890128.
