The LCM of 368,943,688,798 is 258864816.
Find LCM of 368,943,688,798 with Prime Factorization
| 2 | 368, 943, 688, 798 |
| 2 | 184, 943, 344, 399 |
| 2 | 92, 943, 172, 399 |
| 2 | 46, 943, 86, 399 |
| 23 | 23, 943, 43, 399 |
| 1, 41, 43, 399 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 23 x 1 x 41 x 43 x 399 = 258864816
Therefore, the lowest common multiple of 368,943,688,798 is 258864816.
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.
368 x 943 x 688 x 798 = 190524504576
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.
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
943 : 1, 23, 41, 943
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 368,943,688,798, is 1.
Now, the common factors can be found like this.
368:2x 2x 2x 2x 23
943:23x 41
688:2x 2x 2x 2x 43
798:2x 3x 7x 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 2x 2x 2x 23 = 736
Therefore, the value for common factors is 736.
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 = 190524504576/(1x736)
LCM = 190524504576/736
LCM = 258864816
Thus, we can understand that the LCM of 368,943,688,798 is 258864816.
