Find LCM of 494,989,243,313,990 with Prime Factorization
| 2 | 494, 989, 243, 313, 990 |
| 3 | 247, 989, 243, 313, 495 |
| 3 | 247, 989, 81, 313, 165 |
| 247, 989, 27, 313, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 247 x 989 x 27 x 313 x 55 = 2043791276670
Therefore, the lowest common multiple of 494,989,243,313,990 is 2043791276670.
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.
494 x 989 x 243 x 313 x 990 = 36788242980060
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.
494 : 1, 2, 13, 19, 26, 38, 247, 494
989 : 1, 23, 43, 989
243 : 1, 3, 9, 27, 81, 243
313 : 1, 313
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 494,989,243,313,990, is 1.
Now, the common factors can be found like this.
494:2x 13x 19
989:23x 43
243:3x 3x 3x 3x 3
313:313
990:2x 3x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 36788242980060/(1x18)
LCM = 36788242980060/18
LCM = 2043791276670
Thus, we can understand that the LCM of 494,989,243,313,990 is 2043791276670.
