Given numbers are 867,954,731,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 867,954,731,644 is 3817425276.
Find LCM of 867,954,731,644 with Prime Factorization
2 | 867, 954, 731, 644 |
3 | 867, 477, 731, 322 |
17 | 289, 159, 731, 322 |
17, 159, 43, 322 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 17 x 159 x 43 x 322 = 3817425276
Therefore, the lowest common multiple of 867,954,731,644 is 3817425276.
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.
867 x 954 x 731 x 644 = 389377378152
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.
867 : 1, 3, 17, 51, 289, 867
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
731 : 1, 17, 43, 731
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,954,731,644, is 1.
Now, the common factors can be found like this.
867:3x 17x 17
954:2x 3x 3x 53
731:17x 43
644:2x 2x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17 = 102
Therefore, the value for common factors is 102.
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 = 389377378152/(1x102)
LCM = 389377378152/102
LCM = 3817425276
Thus, we can understand that the LCM of 867,954,731,644 is 3817425276.
