Find LCM of 117,630,486,815,515 with Prime Factorization
| 2 | 117, 630, 486, 815, 515 |
| 3 | 117, 315, 243, 815, 515 |
| 3 | 39, 105, 81, 815, 515 |
| 5 | 13, 35, 27, 815, 515 |
| 13, 7, 27, 163, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 13 x 7 x 27 x 163 x 103 = 3712551570
Therefore, the lowest common multiple of 117,630,486,815,515 is 3712551570.
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.
117 x 630 x 486 x 815 x 515 = 15035833858500
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.
117 : 1, 3, 9, 13, 39, 117
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
815 : 1, 5, 163, 815
515 : 1, 5, 103, 515
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 117,630,486,815,515, is 1.
Now, the common factors can be found like this.
117:3x 3x 13
630:2x 3x 3x 5x 7
486:2x 3x 3x 3x 3x 3
815:5x 163
515:5x 103
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 3x 3x 3x 5x 5 = 4050
Therefore, the value for common factors is 4050.
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 = 15035833858500/(1x4050)
LCM = 15035833858500/4050
LCM = 3712551570
Thus, we can understand that the LCM of 117,630,486,815,515 is 3712551570.
