Given numbers are 321,710,568,455,790
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 321,710,568,455,790 is 6553779960.
Find LCM of 321,710,568,455,790 with Prime Factorization
| 2 | 321, 710, 568, 455, 790 |
| 5 | 321, 355, 284, 455, 395 |
| 71 | 321, 71, 284, 91, 79 |
| 321, 1, 4, 91, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 71 x 321 x 1 x 4 x 91 x 79 = 6553779960
Therefore, the lowest common multiple of 321,710,568,455,790 is 6553779960.
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.
321 x 710 x 568 x 455 x 790 = 46531837716000
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.
321 : 1, 3, 107, 321
710 : 1, 2, 5, 10, 71, 142, 355, 710
568 : 1, 2, 4, 8, 71, 142, 284, 568
455 : 1, 5, 7, 13, 35, 65, 91, 455
790 : 1, 2, 5, 10, 79, 158, 395, 790
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,710,568,455,790, is 1.
Now, the common factors can be found like this.
321:3x 107
710:2x 5x 71
568:2x 2x 2x 71
455:5x 7x 13
790:2x 5x 79
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 5x 5x 71 = 7100
Therefore, the value for common factors is 7100.
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 = 46531837716000/(1x7100)
LCM = 46531837716000/7100
LCM = 6553779960
Thus, we can understand that the LCM of 321,710,568,455,790 is 6553779960.
