Given numbers are 721,701,206,430,819
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,701,206,430,819 is 25427730510.
Find LCM of 721,701,206,430,819 with Prime Factorization
| 2 | 721, 701, 206, 430, 819 |
| 7 | 721, 701, 103, 215, 819 |
| 103 | 103, 701, 103, 215, 117 |
| 1, 701, 1, 215, 117 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 103 x 1 x 701 x 1 x 215 x 117 = 25427730510
Therefore, the lowest common multiple of 721,701,206,430,819 is 25427730510.
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.
721 x 701 x 206 x 430 x 819 = 36666787395420
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.
721 : 1, 7, 103, 721
701 : 1, 701
206 : 1, 2, 103, 206
430 : 1, 2, 5, 10, 43, 86, 215, 430
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,701,206,430,819, is 1.
Now, the common factors can be found like this.
721:7x 103
701:701
206:2x 103
430:2x 5x 43
819:3x 3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 103 = 1442
Therefore, the value for common factors is 1442.
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 = 36666787395420/(1x1442)
LCM = 36666787395420/1442
LCM = 25427730510
Thus, we can understand that the LCM of 721,701,206,430,819 is 25427730510.
