Given numbers are 821,596,486,947
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,596,486,947 is 112601887236.
Find LCM of 821,596,486,947 with Prime Factorization
| 2 | 821, 596, 486, 947 |
| 821, 298, 243, 947 |
Multiply the prime numbers at the bottom and the left side.
2 x 821 x 298 x 243 x 947 = 112601887236
Therefore, the lowest common multiple of 821,596,486,947 is 112601887236.
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.
821 x 596 x 486 x 947 = 225203774472
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.
821 : 1, 821
596 : 1, 2, 4, 149, 298, 596
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,596,486,947, is 1.
Now, the common factors can be found like this.
821:821
596:2x 2x 149
486:2x 3x 3x 3x 3x 3
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.
2 = 2
Therefore, the value for common factors is 2.
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 = 225203774472/(1x2)
LCM = 225203774472/2
LCM = 112601887236
Thus, we can understand that the LCM of 821,596,486,947 is 112601887236.
