Given numbers are 868,256,187,135,407
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 868,256,187,135,407 is 51889178880.
Find LCM of 868,256,187,135,407 with Prime Factorization
| 2 | 868, 256, 187, 135, 407 |
| 2 | 434, 128, 187, 135, 407 |
| 11 | 217, 64, 187, 135, 407 |
| 217, 64, 17, 135, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 217 x 64 x 17 x 135 x 37 = 51889178880
Therefore, the lowest common multiple of 868,256,187,135,407 is 51889178880.
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.
868 x 256 x 187 x 135 x 407 = 2283123870720
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.
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
187 : 1, 11, 17, 187
135 : 1, 3, 5, 9, 15, 27, 45, 135
407 : 1, 11, 37, 407
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,256,187,135,407, is 1.
Now, the common factors can be found like this.
868:2x 2x 7x 31
256:2x 2x 2x 2x 2x 2x 2x 2
187:11x 17
135:3x 3x 3x 5
407:11x 37
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 11 = 44
Therefore, the value for common factors is 44.
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 = 2283123870720/(1x44)
LCM = 2283123870720/44
LCM = 51889178880
Thus, we can understand that the LCM of 868,256,187,135,407 is 51889178880.
