Given numbers are 861,831,500,126,694
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,831,500,126,694 is 124137688500.
Find LCM of 861,831,500,126,694 with Prime Factorization
| 2 | 861, 831, 500, 126, 694 |
| 3 | 861, 831, 250, 63, 347 |
| 7 | 287, 277, 250, 21, 347 |
| 41, 277, 250, 3, 347 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 41 x 277 x 250 x 3 x 347 = 124137688500
Therefore, the lowest common multiple of 861,831,500,126,694 is 124137688500.
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.
861 x 831 x 500 x 126 x 694 = 31282697502000
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
831 : 1, 3, 277, 831
500 : 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
694 : 1, 2, 347, 694
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,831,500,126,694, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
831:3x 277
500:2x 2x 5x 5x 5
126:2x 3x 3x 7
694:2x 347
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 7 = 252
Therefore, the value for common factors is 252.
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 = 31282697502000/(1x252)
LCM = 31282697502000/252
LCM = 124137688500
Thus, we can understand that the LCM of 861,831,500,126,694 is 124137688500.
