Given numbers are 398,635,329,889
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,635,329,889 is 83148170.
Find LCM of 398,635,329,889 with Prime Factorization
| 7 | 398, 635, 329, 889 |
| 127 | 398, 635, 47, 127 |
| 398, 5, 47, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 127 x 398 x 5 x 47 x 1 = 83148170
Therefore, the lowest common multiple of 398,635,329,889 is 83148170.
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 635 x 329 x 889 = 73918723130
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
635 : 1, 5, 127, 635
329 : 1, 7, 47, 329
889 : 1, 7, 127, 889
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,635,329,889, is 1.
Now, the common factors can be found like this.
398:2x 199
635:5x 127
329:7x 47
889:7x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 127 = 889
Therefore, the value for common factors is 889.
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 = 73918723130/(1x889)
LCM = 73918723130/889
LCM = 83148170
Thus, we can understand that the LCM of 398,635,329,889 is 83148170.
