Find LCM of 905,168,460,621,462 with Prime Factorization
| 2 | 905, 168, 460, 621, 462 |
| 2 | 905, 84, 230, 621, 231 |
| 3 | 905, 42, 115, 621, 231 |
| 5 | 905, 14, 115, 207, 77 |
| 7 | 181, 14, 23, 207, 77 |
| 23 | 181, 2, 23, 207, 11 |
| 181, 2, 1, 9, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 23 x 181 x 2 x 1 x 9 x 11 = 346195080
Therefore, the lowest common multiple of 905,168,460,621,462 is 346195080.
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.
905 x 168 x 460 x 621 x 462 = 20065466836800
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.
905 : 1, 5, 181, 905
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
621 : 1, 3, 9, 23, 27, 69, 207, 621
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,168,460,621,462, is 1.
Now, the common factors can be found like this.
905:5x 181
168:2x 2x 2x 3x 7
460:2x 2x 5x 23
621:3x 3x 3x 23
462:2x 3x 7x 11
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 3x 3x 5x 7x 23 = 57960
Therefore, the value for common factors is 57960.
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 = 20065466836800/(1x57960)
LCM = 20065466836800/57960
LCM = 346195080
Thus, we can understand that the LCM of 905,168,460,621,462 is 346195080.
