Given numbers are 667,615,965,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 667,615,965,387 is 10212873885.
Find LCM of 667,615,965,387 with Prime Factorization
| 3 | 667, 615, 965, 387 |
| 5 | 667, 205, 965, 129 |
| 667, 41, 193, 129 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 667 x 41 x 193 x 129 = 10212873885
Therefore, the lowest common multiple of 667,615,965,387 is 10212873885.
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.
667 x 615 x 965 x 387 = 153193108275
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.
667 : 1, 23, 29, 667
615 : 1, 3, 5, 15, 41, 123, 205, 615
965 : 1, 5, 193, 965
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,615,965,387, is 1.
Now, the common factors can be found like this.
667:23x 29
615:3x 5x 41
965:5x 193
387:3x 3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 153193108275/(1x15)
LCM = 153193108275/15
LCM = 10212873885
Thus, we can understand that the LCM of 667,615,965,387 is 10212873885.
