Given numbers are 398,180,681,816,588
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,180,681,816,588 is 27092958480.
Find LCM of 398,180,681,816,588 with Prime Factorization
| 2 | 398, 180, 681, 816, 588 |
| 2 | 199, 90, 681, 408, 294 |
| 3 | 199, 45, 681, 204, 147 |
| 199, 15, 227, 68, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 199 x 15 x 227 x 68 x 49 = 27092958480
Therefore, the lowest common multiple of 398,180,681,816,588 is 27092958480.
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 180 x 681 x 816 x 588 = 23408316126720
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
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
681 : 1, 3, 227, 681
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
588 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 49, 84, 98, 147, 196, 294, 588
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,180,681,816,588, is 1.
Now, the common factors can be found like this.
398:2x 199
180:2x 2x 3x 3x 5
681:3x 227
816:2x 2x 2x 2x 3x 17
588:2x 2x 3x 7x 7
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 2x 2x 2x 3x 3x 3 = 864
Therefore, the value for common factors is 864.
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 = 23408316126720/(1x864)
LCM = 23408316126720/864
LCM = 27092958480
Thus, we can understand that the LCM of 398,180,681,816,588 is 27092958480.
