Given numbers are 189,894,746,414,820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 189,894,746,414,820 is 198106439580.
Find LCM of 189,894,746,414,820 with Prime Factorization
| 2 | 189, 894, 746, 414, 820 |
| 3 | 189, 447, 373, 207, 410 |
| 3 | 63, 149, 373, 69, 410 |
| 21, 149, 373, 23, 410 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 21 x 149 x 373 x 23 x 410 = 198106439580
Therefore, the lowest common multiple of 189,894,746,414,820 is 198106439580.
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.
189 x 894 x 746 x 414 x 820 = 42790990949280
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
894 : 1, 2, 3, 6, 149, 298, 447, 894
746 : 1, 2, 373, 746
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,894,746,414,820, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
894:2x 3x 149
746:2x 373
414:2x 3x 3x 23
820:2x 2x 5x 41
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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 42790990949280/(1x216)
LCM = 42790990949280/216
LCM = 198106439580
Thus, we can understand that the LCM of 189,894,746,414,820 is 198106439580.
