Given numbers are 830,449,574,171
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 830,449,574,171 is 18289525590.
Find LCM of 830,449,574,171 with Prime Factorization
| 2 | 830, 449, 574, 171 |
| 415, 449, 287, 171 |
Multiply the prime numbers at the bottom and the left side.
2 x 415 x 449 x 287 x 171 = 18289525590
Therefore, the lowest common multiple of 830,449,574,171 is 18289525590.
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.
830 x 449 x 574 x 171 = 36579051180
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.
830 : 1, 2, 5, 10, 83, 166, 415, 830
449 : 1, 449
574 : 1, 2, 7, 14, 41, 82, 287, 574
171 : 1, 3, 9, 19, 57, 171
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 830,449,574,171, is 1.
Now, the common factors can be found like this.
830:2x 5x 83
449:449
574:2x 7x 41
171:3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 36579051180/(1x2)
LCM = 36579051180/2
LCM = 18289525590
Thus, we can understand that the LCM of 830,449,574,171 is 18289525590.
