Given numbers are 800,208,979,419,742
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 800,208,979,419,742 is 1582719538400.
Find LCM of 800,208,979,419,742 with Prime Factorization
| 2 | 800, 208, 979, 419, 742 |
| 2 | 400, 104, 979, 419, 371 |
| 2 | 200, 52, 979, 419, 371 |
| 2 | 100, 26, 979, 419, 371 |
| 50, 13, 979, 419, 371 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 50 x 13 x 979 x 419 x 371 = 1582719538400
Therefore, the lowest common multiple of 800,208,979,419,742 is 1582719538400.
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.
800 x 208 x 979 x 419 x 742 = 50647025228800
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.
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
979 : 1, 11, 89, 979
419 : 1, 419
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 800,208,979,419,742, is 1.
Now, the common factors can be found like this.
800:2x 2x 2x 2x 2x 5x 5
208:2x 2x 2x 2x 13
979:11x 89
419:419
742:2x 7x 53
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 2x 2x 2 = 32
Therefore, the value for common factors is 32.
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 = 50647025228800/(1x32)
LCM = 50647025228800/32
LCM = 1582719538400
Thus, we can understand that the LCM of 800,208,979,419,742 is 1582719538400.
