Find LCM of 808,981,981,748,645 with Prime Factorization
| 2 | 808, 981, 981, 748, 645 |
| 2 | 404, 981, 981, 374, 645 |
| 3 | 202, 981, 981, 187, 645 |
| 3 | 202, 327, 327, 187, 215 |
| 109 | 202, 109, 109, 187, 215 |
| 202, 1, 1, 187, 215 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 109 x 202 x 1 x 1 x 187 x 215 = 31868412840
Therefore, the lowest common multiple of 808,981,981,748,645 is 31868412840.
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.
808 x 981 x 981 x 748 x 645 = 375154955952480
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
981 : 1, 3, 9, 109, 327, 981
981 : 1, 3, 9, 109, 327, 981
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,981,981,748,645, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
981:3x 3x 109
981:3x 3x 109
748:2x 2x 11x 17
645:3x 5x 43
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 3x 3x 3x 109 = 11772
Therefore, the value for common factors is 11772.
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 = 375154955952480/(1x11772)
LCM = 375154955952480/11772
LCM = 31868412840
Thus, we can understand that the LCM of 808,981,981,748,645 is 31868412840.
