The LCM of 826,169,780,452 is 473223660.
Find LCM of 826,169,780,452 with Prime Factorization
| 2 | 826, 169, 780, 452 |
| 2 | 413, 169, 390, 226 |
| 13 | 413, 169, 195, 113 |
| 413, 13, 15, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 413 x 13 x 15 x 113 = 473223660
Therefore, the lowest common multiple of 826,169,780,452 is 473223660.
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.
826 x 169 x 780 x 452 = 49215260640
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.
826 : 1, 2, 7, 14, 59, 118, 413, 826
169 : 1, 13, 169
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
452 : 1, 2, 4, 113, 226, 452
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 826,169,780,452, is 1.
Now, the common factors can be found like this.
826:2x 7x 59
169:13x 13
780:2x 2x 3x 5x 13
452:2x 2x 113
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 13 = 104
Therefore, the value for common factors is 104.
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 = 49215260640/(1x104)
LCM = 49215260640/104
LCM = 473223660
Thus, we can understand that the LCM of 826,169,780,452 is 473223660.
