Given numbers are 894,398,138,716,891
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 894,398,138,716,891 is 435068767188.
Find LCM of 894,398,138,716,891 with Prime Factorization
| 2 | 894, 398, 138, 716, 891 |
| 3 | 447, 199, 69, 358, 891 |
| 149, 199, 23, 358, 297 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 149 x 199 x 23 x 358 x 297 = 435068767188
Therefore, the lowest common multiple of 894,398,138,716,891 is 435068767188.
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.
894 x 398 x 138 x 716 x 891 = 31324951237536
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.
894 : 1, 2, 3, 6, 149, 298, 447, 894
398 : 1, 2, 199, 398
138 : 1, 2, 3, 6, 23, 46, 69, 138
716 : 1, 2, 4, 179, 358, 716
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 894,398,138,716,891, is 1.
Now, the common factors can be found like this.
894:2x 3x 149
398:2x 199
138:2x 3x 23
716:2x 2x 179
891:3x 3x 3x 3x 11
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 2x 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 31324951237536/(1x72)
LCM = 31324951237536/72
LCM = 435068767188
Thus, we can understand that the LCM of 894,398,138,716,891 is 435068767188.
