Find LCM of 462,786,605,309,987 with Prime Factorization
| 2 | 462, 786, 605, 309, 987 |
| 3 | 231, 393, 605, 309, 987 |
| 7 | 77, 131, 605, 103, 329 |
| 11 | 11, 131, 605, 103, 47 |
| 1, 131, 55, 103, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 1 x 131 x 55 x 103 x 47 = 16114285110
Therefore, the lowest common multiple of 462,786,605,309,987 is 16114285110.
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.
462 x 786 x 605 x 309 x 987 = 67003197487380
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.
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
786 : 1, 2, 3, 6, 131, 262, 393, 786
605 : 1, 5, 11, 55, 121, 605
309 : 1, 3, 103, 309
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 462,786,605,309,987, is 1.
Now, the common factors can be found like this.
462:2x 3x 7x 11
786:2x 3x 131
605:5x 11x 11
309:3x 103
987:3x 7x 47
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 3x 7x 11 = 4158
Therefore, the value for common factors is 4158.
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 = 67003197487380/(1x4158)
LCM = 67003197487380/4158
LCM = 16114285110
Thus, we can understand that the LCM of 462,786,605,309,987 is 16114285110.
