Given numbers are 398,388,622,611
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,388,622,611 is 14671901452.
Find LCM of 398,388,622,611 with Prime Factorization
| 2 | 398, 388, 622, 611 |
| 199, 194, 311, 611 |
Multiply the prime numbers at the bottom and the left side.
2 x 199 x 194 x 311 x 611 = 14671901452
Therefore, the lowest common multiple of 398,388,622,611 is 14671901452.
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 388 x 622 x 611 = 58687605808
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
388 : 1, 2, 4, 97, 194, 388
622 : 1, 2, 311, 622
611 : 1, 13, 47, 611
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,388,622,611, is 1.
Now, the common factors can be found like this.
398:2x 199
388:2x 2x 97
622:2x 311
611:13x 47
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 = 58687605808/(1x4)
LCM = 58687605808/4
LCM = 14671901452
Thus, we can understand that the LCM of 398,388,622,611 is 14671901452.
