Given numbers are 230,673,345,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 230,673,345,981 is 151848990.
Find LCM of 230,673,345,981 with Prime Factorization
| 3 | 230, 673, 345, 981 |
| 5 | 230, 673, 115, 327 |
| 23 | 46, 673, 23, 327 |
| 2, 673, 1, 327 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 23 x 2 x 673 x 1 x 327 = 151848990
Therefore, the lowest common multiple of 230,673,345,981 is 151848990.
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.
230 x 673 x 345 x 981 = 52387901550
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.
230 : 1, 2, 5, 10, 23, 46, 115, 230
673 : 1, 673
345 : 1, 3, 5, 15, 23, 69, 115, 345
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 230,673,345,981, is 1.
Now, the common factors can be found like this.
230:2x 5x 23
673:673
345:3x 5x 23
981:3x 3x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 23 = 345
Therefore, the value for common factors is 345.
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 = 52387901550/(1x345)
LCM = 52387901550/345
LCM = 151848990
Thus, we can understand that the LCM of 230,673,345,981 is 151848990.
