Given numbers are 579,470,785,400
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 579,470,785,400 is 1708976400.
Find LCM of 579,470,785,400 with Prime Factorization
| 2 | 579, 470, 785, 400 |
| 5 | 579, 235, 785, 200 |
| 579, 47, 157, 40 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 579 x 47 x 157 x 40 = 1708976400
Therefore, the lowest common multiple of 579,470,785,400 is 1708976400.
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.
579 x 470 x 785 x 400 = 85448820000
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.
579 : 1, 3, 193, 579
470 : 1, 2, 5, 10, 47, 94, 235, 470
785 : 1, 5, 157, 785
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 579,470,785,400, is 1.
Now, the common factors can be found like this.
579:3x 193
470:2x 5x 47
785:5x 157
400:2x 2x 2x 2x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5 = 50
Therefore, the value for common factors is 50.
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 = 85448820000/(1x50)
LCM = 85448820000/50
LCM = 1708976400
Thus, we can understand that the LCM of 579,470,785,400 is 1708976400.
