Find LCM of 676,252,837,945 with Prime Factorization
| 2 | 676, 252, 837, 945 |
| 2 | 338, 126, 837, 945 |
| 3 | 169, 63, 837, 945 |
| 3 | 169, 21, 279, 315 |
| 3 | 169, 7, 93, 105 |
| 7 | 169, 7, 31, 35 |
| 169, 1, 31, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 7 x 169 x 1 x 31 x 5 = 19803420
Therefore, the lowest common multiple of 676,252,837,945 is 19803420.
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.
676 x 252 x 837 x 945 = 134742469680
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
837 : 1, 3, 9, 27, 31, 93, 279, 837
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,252,837,945, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
252:2x 2x 3x 3x 7
837:3x 3x 3x 31
945:3x 3x 3x 5x 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 3x 3x 3x 3x 3x 7 = 6804
Therefore, the value for common factors is 6804.
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 = 134742469680/(1x6804)
LCM = 134742469680/6804
LCM = 19803420
Thus, we can understand that the LCM of 676,252,837,945 is 19803420.
