Given numbers are 894,649,561,913
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 894,649,561,913 is 818670666.
Find LCM of 894,649,561,913 with Prime Factorization
| 3 | 894, 649, 561, 913 |
| 11 | 298, 649, 187, 913 |
| 298, 59, 17, 83 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 298 x 59 x 17 x 83 = 818670666
Therefore, the lowest common multiple of 894,649,561,913 is 818670666.
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 649 x 561 x 913 = 297177451758
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
649 : 1, 11, 59, 649
561 : 1, 3, 11, 17, 33, 51, 187, 561
913 : 1, 11, 83, 913
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 894,649,561,913, is 1.
Now, the common factors can be found like this.
894:2x 3x 149
649:11x 59
561:3x 11x 17
913:11x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 11 = 363
Therefore, the value for common factors is 363.
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 = 297177451758/(1x363)
LCM = 297177451758/363
LCM = 818670666
Thus, we can understand that the LCM of 894,649,561,913 is 818670666.
