Given numbers are 398,209,957,597
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,209,957,597 is 7236834.
Find LCM of 398,209,957,597 with Prime Factorization
| 3 | 398, 209, 957, 597 |
| 11 | 398, 209, 319, 199 |
| 199 | 398, 19, 29, 199 |
| 2, 19, 29, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 199 x 2 x 19 x 29 x 1 = 7236834
Therefore, the lowest common multiple of 398,209,957,597 is 7236834.
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 209 x 957 x 597 = 47524288878
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
209 : 1, 11, 19, 209
957 : 1, 3, 11, 29, 33, 87, 319, 957
597 : 1, 3, 199, 597
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,209,957,597, is 1.
Now, the common factors can be found like this.
398:2x 199
209:11x 19
957:3x 11x 29
597:3x 199
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 199 = 6567
Therefore, the value for common factors is 6567.
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 = 47524288878/(1x6567)
LCM = 47524288878/6567
LCM = 7236834
Thus, we can understand that the LCM of 398,209,957,597 is 7236834.
