Given numbers are 129,384,670,749,892
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 129,384,670,749,892 is 923913191040.
Find LCM of 129,384,670,749,892 with Prime Factorization
| 2 | 129, 384, 670, 749, 892 |
| 2 | 129, 192, 335, 749, 446 |
| 3 | 129, 96, 335, 749, 223 |
| 43, 32, 335, 749, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 43 x 32 x 335 x 749 x 223 = 923913191040
Therefore, the lowest common multiple of 129,384,670,749,892 is 923913191040.
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.
129 x 384 x 670 x 749 x 892 = 22173916584960
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.
129 : 1, 3, 43, 129
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
670 : 1, 2, 5, 10, 67, 134, 335, 670
749 : 1, 7, 107, 749
892 : 1, 2, 4, 223, 446, 892
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 129,384,670,749,892, is 1.
Now, the common factors can be found like this.
129:3x 43
384:2x 2x 2x 2x 2x 2x 2x 3
670:2x 5x 67
749:7x 107
892:2x 2x 223
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 3 = 24
Therefore, the value for common factors is 24.
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 = 22173916584960/(1x24)
LCM = 22173916584960/24
LCM = 923913191040
Thus, we can understand that the LCM of 129,384,670,749,892 is 923913191040.
