Given numbers are 380,681,836,281,908
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 380,681,836,281,908 is 799888980.
Find LCM of 380,681,836,281,908 with Prime Factorization
| 2 | 380, 681, 836, 281, 908 |
| 2 | 190, 681, 418, 281, 454 |
| 19 | 95, 681, 209, 281, 227 |
| 227 | 5, 681, 11, 281, 227 |
| 5, 3, 11, 281, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 227 x 5 x 3 x 11 x 281 x 1 = 799888980
Therefore, the lowest common multiple of 380,681,836,281,908 is 799888980.
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.
380 x 681 x 836 x 281 x 908 = 55198738731840
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.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
681 : 1, 3, 227, 681
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
281 : 1, 281
908 : 1, 2, 4, 227, 454, 908
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,681,836,281,908, is 1.
Now, the common factors can be found like this.
380:2x 2x 5x 19
681:3x 227
836:2x 2x 11x 19
281:281
908:2x 2x 227
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 19x 227 = 69008
Therefore, the value for common factors is 69008.
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 = 55198738731840/(1x69008)
LCM = 55198738731840/69008
LCM = 799888980
Thus, we can understand that the LCM of 380,681,836,281,908 is 799888980.
