Given numbers are 398,632,401
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,632,401 is 50432968.
Find LCM of 398,632,401 with Prime Factorization
| 2 | 398, 632, 401 |
| 199, 316, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 199 x 316 x 401 = 50432968
Therefore, the lowest common multiple of 398,632,401 is 50432968.
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 632 x 401 = 100865936
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
632 : 1, 2, 4, 8, 79, 158, 316, 632
401 : 1, 401
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,632,401, is 1.
Now, the common factors can be found like this.
398:2x 199
632:2x 2x 2x 79
401:401
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 100865936/(1x2)
LCM = 100865936/2
LCM = 50432968
Thus, we can understand that the LCM of 398,632,401 is 50432968.
