Find LCM of 804,492,987,689,511 with Prime Factorization
| 2 | 804, 492, 987, 689, 511 |
| 2 | 402, 246, 987, 689, 511 |
| 3 | 201, 123, 987, 689, 511 |
| 7 | 67, 41, 329, 689, 511 |
| 67, 41, 47, 689, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 67 x 41 x 47 x 689 x 73 = 545478811332
Therefore, the lowest common multiple of 804,492,987,689,511 is 545478811332.
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.
804 x 492 x 987 x 689 x 511 = 137460660455664
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.
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
987 : 1, 3, 7, 21, 47, 141, 329, 987
689 : 1, 13, 53, 689
511 : 1, 7, 73, 511
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 804,492,987,689,511, is 1.
Now, the common factors can be found like this.
804:2x 2x 3x 67
492:2x 2x 3x 41
987:3x 7x 47
689:13x 53
511:7x 73
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 7 = 252
Therefore, the value for common factors is 252.
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 = 137460660455664/(1x252)
LCM = 137460660455664/252
LCM = 545478811332
Thus, we can understand that the LCM of 804,492,987,689,511 is 545478811332.
