Given numbers are 874,538,810,860
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,538,810,860 is 8188741980.
Find LCM of 874,538,810,860 with Prime Factorization
| 2 | 874, 538, 810, 860 |
| 5 | 437, 269, 405, 430 |
| 437, 269, 81, 86 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 437 x 269 x 81 x 86 = 8188741980
Therefore, the lowest common multiple of 874,538,810,860 is 8188741980.
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.
874 x 538 x 810 x 860 = 327549679200
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
538 : 1, 2, 269, 538
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,538,810,860, is 2.
Now, the common factors can be found like this.
874:2x 19x 23
538:2x 269
810:2x 3x 3x 3x 3x 5
860:2x 2x 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 5 = 20
Therefore, the value for common factors is 20.
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 = 327549679200/(2x20)
LCM = 327549679200/40
LCM = 8188741980
Thus, we can understand that the LCM of 874,538,810,860 is 8188741980.
