Given numbers are 187,394,989,957
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 187,394,989,957 is 6339476154.
Find LCM of 187,394,989,957 with Prime Factorization
| 11 | 187, 394, 989, 957 |
| 17, 394, 989, 87 |
Multiply the prime numbers at the bottom and the left side.
11 x 17 x 394 x 989 x 87 = 6339476154
Therefore, the lowest common multiple of 187,394,989,957 is 6339476154.
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.
187 x 394 x 989 x 957 = 69734237694
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.
187 : 1, 11, 17, 187
394 : 1, 2, 197, 394
989 : 1, 23, 43, 989
957 : 1, 3, 11, 29, 33, 87, 319, 957
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,394,989,957, is 1.
Now, the common factors can be found like this.
187:11x 17
394:2x 197
989:23x 43
957:3x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 69734237694/(1x11)
LCM = 69734237694/11
LCM = 6339476154
Thus, we can understand that the LCM of 187,394,989,957 is 6339476154.
