Find LCM of 981,109,588,869,812 with Prime Factorization
| 2 | 981, 109, 588, 869, 812 |
| 2 | 981, 109, 294, 869, 406 |
| 3 | 981, 109, 147, 869, 203 |
| 7 | 327, 109, 49, 869, 203 |
| 109 | 327, 109, 7, 869, 29 |
| 3, 1, 7, 869, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 109 x 3 x 1 x 7 x 869 x 29 = 4845547476
Therefore, the lowest common multiple of 981,109,588,869,812 is 4845547476.
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 109 x 588 x 869 x 812 = 44365832690256
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
109 : 1, 109
588 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 49, 84, 98, 147, 196, 294, 588
869 : 1, 11, 79, 869
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,109,588,869,812, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
109:109
588:2x 2x 3x 7x 7
869:11x 79
812:2x 2x 7x 29
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 7x 109 = 9156
Therefore, the value for common factors is 9156.
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 = 44365832690256/(1x9156)
LCM = 44365832690256/9156
LCM = 4845547476
Thus, we can understand that the LCM of 981,109,588,869,812 is 4845547476.
