Given numbers are 398,678,611,698
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,678,611,698 is 28770632358.
Find LCM of 398,678,611,698 with Prime Factorization
| 2 | 398, 678, 611, 698 |
| 199, 339, 611, 349 |
Multiply the prime numbers at the bottom and the left side.
2 x 199 x 339 x 611 x 349 = 28770632358
Therefore, the lowest common multiple of 398,678,611,698 is 28770632358.
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 678 x 611 x 698 = 115082529432
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
678 : 1, 2, 3, 6, 113, 226, 339, 678
611 : 1, 13, 47, 611
698 : 1, 2, 349, 698
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,678,611,698, is 1.
Now, the common factors can be found like this.
398:2x 199
678:2x 3x 113
611:13x 47
698:2x 349
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 115082529432/(1x4)
LCM = 115082529432/4
LCM = 28770632358
Thus, we can understand that the LCM of 398,678,611,698 is 28770632358.
