Given numbers are 398,329,861,433
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,329,861,433 is 6973839978.
Find LCM of 398,329,861,433 with Prime Factorization
| 7 | 398, 329, 861, 433 |
| 398, 47, 123, 433 |
Multiply the prime numbers at the bottom and the left side.
7 x 398 x 47 x 123 x 433 = 6973839978
Therefore, the lowest common multiple of 398,329,861,433 is 6973839978.
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 329 x 861 x 433 = 48816879846
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
329 : 1, 7, 47, 329
861 : 1, 3, 7, 21, 41, 123, 287, 861
433 : 1, 433
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,329,861,433, is 1.
Now, the common factors can be found like this.
398:2x 199
329:7x 47
861:3x 7x 41
433:433
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 48816879846/(1x7)
LCM = 48816879846/7
LCM = 6973839978
Thus, we can understand that the LCM of 398,329,861,433 is 6973839978.
