Given numbers are 398,208,932,202
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,208,932,202 is 974077936.
Find LCM of 398,208,932,202 with Prime Factorization
| 2 | 398, 208, 932, 202 |
| 2 | 199, 104, 466, 101 |
| 199, 52, 233, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 199 x 52 x 233 x 101 = 974077936
Therefore, the lowest common multiple of 398,208,932,202 is 974077936.
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 208 x 932 x 202 = 15585246976
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
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
932 : 1, 2, 4, 233, 466, 932
202 : 1, 2, 101, 202
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,208,932,202, is 2.
Now, the common factors can be found like this.
398:2x 199
208:2x 2x 2x 2x 13
932:2x 2x 233
202:2x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2 = 8
Therefore, the value for common factors is 8.
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 = 15585246976/(2x8)
LCM = 15585246976/16
LCM = 974077936
Thus, we can understand that the LCM of 398,208,932,202 is 974077936.
