Find LCM of 988,705,517,187,621 with Prime Factorization
| 3 | 988, 705, 517, 187, 621 |
| 11 | 988, 235, 517, 187, 207 |
| 47 | 988, 235, 47, 17, 207 |
| 988, 5, 1, 17, 207 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 47 x 988 x 5 x 1 x 17 x 207 = 26962366860
Therefore, the lowest common multiple of 988,705,517,187,621 is 26962366860.
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.
988 x 705 x 517 x 187 x 621 = 41818630999860
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.
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
705 : 1, 3, 5, 15, 47, 141, 235, 705
517 : 1, 11, 47, 517
187 : 1, 11, 17, 187
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,705,517,187,621, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
705:3x 5x 47
517:11x 47
187:11x 17
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 47 = 1551
Therefore, the value for common factors is 1551.
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 = 41818630999860/(1x1551)
LCM = 41818630999860/1551
LCM = 26962366860
Thus, we can understand that the LCM of 988,705,517,187,621 is 26962366860.
