Given numbers are 102,189,721,820,882
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 102,189,721,820,882 is 1899589860.
Find LCM of 102,189,721,820,882 with Prime Factorization
| 2 | 102, 189, 721, 820, 882 |
| 3 | 51, 189, 721, 410, 441 |
| 3 | 17, 63, 721, 410, 147 |
| 7 | 17, 21, 721, 410, 49 |
| 17, 3, 103, 410, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 17 x 3 x 103 x 410 x 7 = 1899589860
Therefore, the lowest common multiple of 102,189,721,820,882 is 1899589860.
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.
102 x 189 x 721 x 820 x 882 = 10052629539120
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.
102 : 1, 2, 3, 6, 17, 34, 51, 102
189 : 1, 3, 7, 9, 21, 27, 63, 189
721 : 1, 7, 103, 721
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 102,189,721,820,882, is 1.
Now, the common factors can be found like this.
102:2x 3x 17
189:3x 3x 3x 7
721:7x 103
820:2x 2x 5x 41
882:2x 3x 3x 7x 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 2x 3x 3x 3x 7x 7 = 5292
Therefore, the value for common factors is 5292.
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 = 10052629539120/(1x5292)
LCM = 10052629539120/5292
LCM = 1899589860
Thus, we can understand that the LCM of 102,189,721,820,882 is 1899589860.
