Find LCM of 828,726,969,589,491 with Prime Factorization
| 2 | 828, 726, 969, 589, 491 |
| 3 | 414, 363, 969, 589, 491 |
| 19 | 138, 121, 323, 589, 491 |
| 138, 121, 17, 31, 491 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 138 x 121 x 17 x 31 x 491 = 492562580004
Therefore, the lowest common multiple of 828,726,969,589,491 is 492562580004.
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.
828 x 726 x 969 x 589 x 491 = 168456402361368
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.
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
969 : 1, 3, 17, 19, 51, 57, 323, 969
589 : 1, 19, 31, 589
491 : 1, 491
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,726,969,589,491, is 1.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
726:2x 3x 11x 11
969:3x 17x 19
589:19x 31
491:491
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 19 = 342
Therefore, the value for common factors is 342.
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 = 168456402361368/(1x342)
LCM = 168456402361368/342
LCM = 492562580004
Thus, we can understand that the LCM of 828,726,969,589,491 is 492562580004.
