Given numbers are 398,327,847,693
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,327,847,693 is 330700986.
Find LCM of 398,327,847,693 with Prime Factorization
| 3 | 398, 327, 847, 693 |
| 7 | 398, 109, 847, 231 |
| 11 | 398, 109, 121, 33 |
| 398, 109, 11, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 398 x 109 x 11 x 3 = 330700986
Therefore, the lowest common multiple of 398,327,847,693 is 330700986.
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 327 x 847 x 693 = 76391927766
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
327 : 1, 3, 109, 327
847 : 1, 7, 11, 77, 121, 847
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,327,847,693, is 1.
Now, the common factors can be found like this.
398:2x 199
327:3x 109
847:7x 11x 11
693:3x 3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 11 = 231
Therefore, the value for common factors is 231.
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 = 76391927766/(1x231)
LCM = 76391927766/231
LCM = 330700986
Thus, we can understand that the LCM of 398,327,847,693 is 330700986.
