Given numbers are 789,435,461,270,830
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 789,435,461,270,830 is 78794613270.
Find LCM of 789,435,461,270,830 with Prime Factorization
| 2 | 789, 435, 461, 270, 830 |
| 3 | 789, 435, 461, 135, 415 |
| 5 | 263, 145, 461, 45, 415 |
| 263, 29, 461, 9, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 263 x 29 x 461 x 9 x 83 = 78794613270
Therefore, the lowest common multiple of 789,435,461,270,830 is 78794613270.
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.
789 x 435 x 461 x 270 x 830 = 35457575971500
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.
789 : 1, 3, 263, 789
435 : 1, 3, 5, 15, 29, 87, 145, 435
461 : 1, 461
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
830 : 1, 2, 5, 10, 83, 166, 415, 830
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,435,461,270,830, is 1.
Now, the common factors can be found like this.
789:3x 263
435:3x 5x 29
461:461
270:2x 3x 3x 3x 5
830:2x 5x 83
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 5 = 450
Therefore, the value for common factors is 450.
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 = 35457575971500/(1x450)
LCM = 35457575971500/450
LCM = 78794613270
Thus, we can understand that the LCM of 789,435,461,270,830 is 78794613270.
