Given numbers are 398,907,946,393
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,907,946,393 is 67103326554.
Find LCM of 398,907,946,393 with Prime Factorization
| 2 | 398, 907, 946, 393 |
| 199, 907, 473, 393 |
Multiply the prime numbers at the bottom and the left side.
2 x 199 x 907 x 473 x 393 = 67103326554
Therefore, the lowest common multiple of 398,907,946,393 is 67103326554.
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 907 x 946 x 393 = 134206653108
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
907 : 1, 907
946 : 1, 2, 11, 22, 43, 86, 473, 946
393 : 1, 3, 131, 393
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,907,946,393, is 1.
Now, the common factors can be found like this.
398:2x 199
907:907
946:2x 11x 43
393:3x 131
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 = 134206653108/(1x2)
LCM = 134206653108/2
LCM = 67103326554
Thus, we can understand that the LCM of 398,907,946,393 is 67103326554.
