Given numbers are 863,189,154,686,357
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 863,189,154,686,357 is 2989098882.
Find LCM of 863,189,154,686,357 with Prime Factorization
| 2 | 863, 189, 154, 686, 357 |
| 3 | 863, 189, 77, 343, 357 |
| 7 | 863, 63, 77, 343, 119 |
| 863, 9, 11, 49, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 863 x 9 x 11 x 49 x 17 = 2989098882
Therefore, the lowest common multiple of 863,189,154,686,357 is 2989098882.
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.
863 x 189 x 154 x 686 x 357 = 6151565499156
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.
863 : 1, 863
189 : 1, 3, 7, 9, 21, 27, 63, 189
154 : 1, 2, 7, 11, 14, 22, 77, 154
686 : 1, 2, 7, 14, 49, 98, 343, 686
357 : 1, 3, 7, 17, 21, 51, 119, 357
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,189,154,686,357, is 1.
Now, the common factors can be found like this.
863:863
189:3x 3x 3x 7
154:2x 7x 11
686:2x 7x 7x 7
357:3x 7x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 7x 7 = 2058
Therefore, the value for common factors is 2058.
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 = 6151565499156/(1x2058)
LCM = 6151565499156/2058
LCM = 2989098882
Thus, we can understand that the LCM of 863,189,154,686,357 is 2989098882.
