Given numbers are 823,242,294,961,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 823,242,294,961,821 is 23099313907362.
Find LCM of 823,242,294,961,821 with Prime Factorization
| 2 | 823, 242, 294, 961, 821 |
| 823, 121, 147, 961, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 823 x 121 x 147 x 961 x 821 = 23099313907362
Therefore, the lowest common multiple of 823,242,294,961,821 is 23099313907362.
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.
823 x 242 x 294 x 961 x 821 = 46198627814724
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.
823 : 1, 823
242 : 1, 2, 11, 22, 121, 242
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
961 : 1, 31, 961
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,242,294,961,821, is 1.
Now, the common factors can be found like this.
823:823
242:2x 11x 11
294:2x 3x 7x 7
961:31x 31
821:821
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 = 46198627814724/(1x2)
LCM = 46198627814724/2
LCM = 23099313907362
Thus, we can understand that the LCM of 823,242,294,961,821 is 23099313907362.
