Given numbers are 281,258,123,820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 281,258,123,820 is 29724180.
Find LCM of 281,258,123,820 with Prime Factorization
| 2 | 281, 258, 123, 820 |
| 3 | 281, 129, 123, 410 |
| 41 | 281, 43, 41, 410 |
| 281, 43, 1, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 41 x 281 x 43 x 1 x 10 = 29724180
Therefore, the lowest common multiple of 281,258,123,820 is 29724180.
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.
281 x 258 x 123 x 820 = 7312148280
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.
281 : 1, 281
258 : 1, 2, 3, 6, 43, 86, 129, 258
123 : 1, 3, 41, 123
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,258,123,820, is 1.
Now, the common factors can be found like this.
281:281
258:2x 3x 43
123:3x 41
820:2x 2x 5x 41
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 41 = 246
Therefore, the value for common factors is 246.
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 = 7312148280/(1x246)
LCM = 7312148280/246
LCM = 29724180
Thus, we can understand that the LCM of 281,258,123,820 is 29724180.
