Find LCM of 813,126,624,336 with Prime Factorization
| 2 | 813, 126, 624, 336 |
| 2 | 813, 63, 312, 168 |
| 2 | 813, 63, 156, 84 |
| 2 | 813, 63, 78, 42 |
| 3 | 813, 63, 39, 21 |
| 7 | 271, 7, 13, 21 |
| 271, 1, 13, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 271 x 1 x 13 x 3 = 3551184
Therefore, the lowest common multiple of 813,126,624,336 is 3551184.
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.
813 x 126 x 624 x 336 = 21477560832
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.
813 : 1, 3, 271, 813
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,126,624,336, is 3.
Now, the common factors can be found like this.
813:3x 271
126:2x 3x 3x 7
624:2x 2x 2x 2x 3x 13
336:2x 2x 2x 2x 3x 7
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 3x 3x 7 = 2016
Therefore, the value for common factors is 2016.
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 = 21477560832/(3x2016)
LCM = 21477560832/6048
LCM = 3551184
Thus, we can understand that the LCM of 813,126,624,336 is 3551184.
