Given numbers are 843,731,909,947
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,731,909,947 is 176822513253.
Find LCM of 843,731,909,947 with Prime Factorization
| 3 | 843, 731, 909, 947 |
| 281, 731, 303, 947 |
Multiply the prime numbers at the bottom and the left side.
3 x 281 x 731 x 303 x 947 = 176822513253
Therefore, the lowest common multiple of 843,731,909,947 is 176822513253.
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.
843 x 731 x 909 x 947 = 530467539759
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.
843 : 1, 3, 281, 843
731 : 1, 17, 43, 731
909 : 1, 3, 9, 101, 303, 909
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,731,909,947, is 1.
Now, the common factors can be found like this.
843:3x 281
731:17x 43
909:3x 3x 101
947:947
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 530467539759/(1x3)
LCM = 530467539759/3
LCM = 176822513253
Thus, we can understand that the LCM of 843,731,909,947 is 176822513253.
