Find LCM of 756,836,231,396 with Prime Factorization
| 2 | 756, 836, 231, 396 |
| 2 | 378, 418, 231, 198 |
| 3 | 189, 209, 231, 99 |
| 3 | 63, 209, 77, 33 |
| 7 | 21, 209, 77, 11 |
| 11 | 3, 209, 11, 11 |
| 3, 19, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 11 x 3 x 19 x 1 x 1 = 158004
Therefore, the lowest common multiple of 756,836,231,396 is 158004.
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.
756 x 836 x 231 x 396 = 57814295616
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.
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
231 : 1, 3, 7, 11, 21, 33, 77, 231
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,836,231,396, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
836:2x 2x 11x 19
231:3x 7x 11
396:2x 2x 3x 3x 11
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 3x 3x 3x 7x 11x 11 = 365904
Therefore, the value for common factors is 365904.
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 = 57814295616/(1x365904)
LCM = 57814295616/365904
LCM = 158004
Thus, we can understand that the LCM of 756,836,231,396 is 158004.
