Given numbers are 830,511,243,210
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 830,511,243,210 is 103063590.
Find LCM of 830,511,243,210 with Prime Factorization
| 2 | 830, 511, 243, 210 |
| 3 | 415, 511, 243, 105 |
| 5 | 415, 511, 81, 35 |
| 7 | 83, 511, 81, 7 |
| 83, 73, 81, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 83 x 73 x 81 x 1 = 103063590
Therefore, the lowest common multiple of 830,511,243,210 is 103063590.
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.
830 x 511 x 243 x 210 = 21643353900
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.
830 : 1, 2, 5, 10, 83, 166, 415, 830
511 : 1, 7, 73, 511
243 : 1, 3, 9, 27, 81, 243
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 830,511,243,210, is 1.
Now, the common factors can be found like this.
830:2x 5x 83
511:7x 73
243:3x 3x 3x 3x 3
210:2x 3x 5x 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 3x 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 21643353900/(1x210)
LCM = 21643353900/210
LCM = 103063590
Thus, we can understand that the LCM of 830,511,243,210 is 103063590.
