Given numbers are 821,884,663,967
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,884,663,967 is 2105441364.
Find LCM of 821,884,663,967 with Prime Factorization
| 13 | 821, 884, 663, 967 |
| 17 | 821, 68, 51, 967 |
| 821, 4, 3, 967 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 821 x 4 x 3 x 967 = 2105441364
Therefore, the lowest common multiple of 821,884,663,967 is 2105441364.
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 884 x 663 x 967 = 465302541444
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
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
663 : 1, 3, 13, 17, 39, 51, 221, 663
967 : 1, 967
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,884,663,967, is 1.
Now, the common factors can be found like this.
821:821
884:2x 2x 13x 17
663:3x 13x 17
967:967
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17 = 221
Therefore, the value for common factors is 221.
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 = 465302541444/(1x221)
LCM = 465302541444/221
LCM = 2105441364
Thus, we can understand that the LCM of 821,884,663,967 is 2105441364.
