The LCM of 821,646,262,334,323 is 11602816982.
Find LCM of 821,646,262,334,323 with Prime Factorization
| 2 | 821, 646, 262, 334, 323 |
| 17 | 821, 323, 131, 167, 323 |
| 19 | 821, 19, 131, 167, 19 |
| 821, 1, 131, 167, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 19 x 821 x 1 x 131 x 167 x 1 = 11602816982
Therefore, the lowest common multiple of 821,646,262,334,323 is 11602816982.
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 646 x 262 x 334 x 323 = 14990839540744
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
646 : 1, 2, 17, 19, 34, 38, 323, 646
262 : 1, 2, 131, 262
334 : 1, 2, 167, 334
323 : 1, 17, 19, 323
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,646,262,334,323, is 1.
Now, the common factors can be found like this.
821:821
646:2x 17x 19
262:2x 131
334:2x 167
323:17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 17x 19 = 1292
Therefore, the value for common factors is 1292.
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 = 14990839540744/(1x1292)
LCM = 14990839540744/1292
LCM = 11602816982
Thus, we can understand that the LCM of 821,646,262,334,323 is 11602816982.
