Given numbers are 234,864,811,666,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 234,864,811,666,645 is 72463304160.
Find LCM of 234,864,811,666,645 with Prime Factorization
| 2 | 234, 864, 811, 666, 645 |
| 3 | 117, 432, 811, 333, 645 |
| 3 | 39, 144, 811, 111, 215 |
| 13, 48, 811, 37, 215 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 13 x 48 x 811 x 37 x 215 = 72463304160
Therefore, the lowest common multiple of 234,864,811,666,645 is 72463304160.
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.
234 x 864 x 811 x 666 x 645 = 70434331643520
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.
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
811 : 1, 811
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 234,864,811,666,645, is 1.
Now, the common factors can be found like this.
234:2x 3x 3x 13
864:2x 2x 2x 2x 2x 3x 3x 3
811:811
666:2x 3x 3x 37
645:3x 5x 43
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 3x 3x 3x 3x 3 = 972
Therefore, the value for common factors is 972.
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 = 70434331643520/(1x972)
LCM = 70434331643520/972
LCM = 72463304160
Thus, we can understand that the LCM of 234,864,811,666,645 is 72463304160.
