Find LCM of 981,624,212,576 with Prime Factorization
| 2 | 981, 624, 212, 576 |
| 2 | 981, 312, 106, 288 |
| 2 | 981, 156, 53, 144 |
| 2 | 981, 78, 53, 72 |
| 3 | 981, 39, 53, 36 |
| 3 | 327, 13, 53, 12 |
| 109, 13, 53, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 109 x 13 x 53 x 4 = 43258176
Therefore, the lowest common multiple of 981,624,212,576 is 43258176.
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 624 x 212 x 576 = 74750128128
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
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
212 : 1, 2, 4, 53, 106, 212
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,624,212,576, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
624:2x 2x 2x 2x 3x 13
212:2x 2x 53
576:2x 2x 2x 2x 2x 2x 3x 3
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 2x 2x 3x 3x 3 = 1728
Therefore, the value for common factors is 1728.
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 = 74750128128/(1x1728)
LCM = 74750128128/1728
LCM = 43258176
Thus, we can understand that the LCM of 981,624,212,576 is 43258176.
