Given numbers are 810,139,669,794,512
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 810,139,669,794,512 is 2551732554240.
Find LCM of 810,139,669,794,512 with Prime Factorization
| 2 | 810, 139, 669, 794, 512 |
| 3 | 405, 139, 669, 397, 256 |
| 135, 139, 223, 397, 256 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 135 x 139 x 223 x 397 x 256 = 2551732554240
Therefore, the lowest common multiple of 810,139,669,794,512 is 2551732554240.
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.
810 x 139 x 669 x 794 x 512 = 30620790650880
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.
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
139 : 1, 139
669 : 1, 3, 223, 669
794 : 1, 2, 397, 794
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,139,669,794,512, is 1.
Now, the common factors can be found like this.
810:2x 3x 3x 3x 3x 5
139:139
669:3x 223
794:2x 397
512:2x 2x 2x 2x 2x 2x 2x 2x 2
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 3 = 12
Therefore, the value for common factors is 12.
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 = 30620790650880/(1x12)
LCM = 30620790650880/12
LCM = 2551732554240
Thus, we can understand that the LCM of 810,139,669,794,512 is 2551732554240.
