Find LCM of 828,899,987,476 with Prime Factorization
| 2 | 828, 899, 987, 476 |
| 2 | 414, 899, 987, 238 |
| 3 | 207, 899, 987, 119 |
| 7 | 69, 899, 329, 119 |
| 69, 899, 47, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 69 x 899 x 47 x 17 = 4163272596
Therefore, the lowest common multiple of 828,899,987,476 is 4163272596.
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 899 x 987 x 476 = 349714898064
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
899 : 1, 29, 31, 899
987 : 1, 3, 7, 21, 47, 141, 329, 987
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,899,987,476, is 1.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
899:29x 31
987:3x 7x 47
476:2x 2x 7x 17
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 7 = 84
Therefore, the value for common factors is 84.
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 = 349714898064/(1x84)
LCM = 349714898064/84
LCM = 4163272596
Thus, we can understand that the LCM of 828,899,987,476 is 4163272596.
