Given numbers are 280,921,873,379,210
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 280,921,873,379,210 is 28441327320.
Find LCM of 280,921,873,379,210 with Prime Factorization
| 2 | 280, 921, 873, 379, 210 |
| 3 | 140, 921, 873, 379, 105 |
| 5 | 140, 307, 291, 379, 35 |
| 7 | 28, 307, 291, 379, 7 |
| 4, 307, 291, 379, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 4 x 307 x 291 x 379 x 1 = 28441327320
Therefore, the lowest common multiple of 280,921,873,379,210 is 28441327320.
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.
280 x 921 x 873 x 379 x 210 = 17918036211600
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.
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
921 : 1, 3, 307, 921
873 : 1, 3, 9, 97, 291, 873
379 : 1, 379
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 280,921,873,379,210, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
921:3x 307
873:3x 3x 97
379:379
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 3x 5x 7 = 630
Therefore, the value for common factors is 630.
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 = 17918036211600/(1x630)
LCM = 17918036211600/630
LCM = 28441327320
Thus, we can understand that the LCM of 280,921,873,379,210 is 28441327320.
