Find LCM of 826,185,754,820,728 with Prime Factorization
| 2 | 826, 185, 754, 820, 728 |
| 2 | 413, 185, 377, 410, 364 |
| 5 | 413, 185, 377, 205, 182 |
| 7 | 413, 37, 377, 41, 182 |
| 13 | 59, 37, 377, 41, 26 |
| 59, 37, 29, 41, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 13 x 59 x 37 x 29 x 41 x 2 = 9447936680
Therefore, the lowest common multiple of 826,185,754,820,728 is 9447936680.
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 185 x 754 x 820 x 728 = 68780979030400
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
185 : 1, 5, 37, 185
754 : 1, 2, 13, 26, 29, 58, 377, 754
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 826,185,754,820,728, is 1.
Now, the common factors can be found like this.
826:2x 7x 59
185:5x 37
754:2x 13x 29
820:2x 2x 5x 41
728:2x 2x 2x 7x 13
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 5x 7x 13 = 7280
Therefore, the value for common factors is 7280.
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 = 68780979030400/(1x7280)
LCM = 68780979030400/7280
LCM = 9447936680
Thus, we can understand that the LCM of 826,185,754,820,728 is 9447936680.
