Find LCM of 981,955,920,506,904 with Prime Factorization
| 2 | 981, 955, 920, 506, 904 |
| 2 | 981, 955, 460, 253, 452 |
| 2 | 981, 955, 230, 253, 226 |
| 5 | 981, 955, 115, 253, 113 |
| 23 | 981, 191, 23, 253, 113 |
| 981, 191, 1, 11, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 23 x 981 x 191 x 1 x 11 x 113 = 214269980760
Therefore, the lowest common multiple of 981,955,920,506,904 is 214269980760.
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 955 x 920 x 506 x 904 = 394256764598400
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
955 : 1, 5, 191, 955
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
506 : 1, 2, 11, 22, 23, 46, 253, 506
904 : 1, 2, 4, 8, 113, 226, 452, 904
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,955,920,506,904, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
955:5x 191
920:2x 2x 2x 5x 23
506:2x 11x 23
904:2x 2x 2x 113
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 5x 23 = 1840
Therefore, the value for common factors is 1840.
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 = 394256764598400/(1x1840)
LCM = 394256764598400/1840
LCM = 214269980760
Thus, we can understand that the LCM of 981,955,920,506,904 is 214269980760.
