Find LCM of 981,416,862,280,675 with Prime Factorization
| 2 | 981, 416, 862, 280, 675 |
| 2 | 981, 208, 431, 140, 675 |
| 2 | 981, 104, 431, 70, 675 |
| 3 | 981, 52, 431, 35, 675 |
| 3 | 327, 52, 431, 35, 225 |
| 5 | 109, 52, 431, 35, 75 |
| 109, 52, 431, 7, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 109 x 52 x 431 x 7 x 15 = 92341922400
Therefore, the lowest common multiple of 981,416,862,280,675 is 92341922400.
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.
981 x 416 x 862 x 280 x 675 = 66486184128000
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.
981 : 1, 3, 9, 109, 327, 981
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
862 : 1, 2, 431, 862
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,416,862,280,675, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
416:2x 2x 2x 2x 2x 13
862:2x 431
280:2x 2x 2x 5x 7
675:3x 3x 3x 5x 5
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 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 66486184128000/(1x720)
LCM = 66486184128000/720
LCM = 92341922400
Thus, we can understand that the LCM of 981,416,862,280,675 is 92341922400.
