Given numbers are 390,374,916,460,308
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 390,374,916,460,308 is 5377712340.
Find LCM of 390,374,916,460,308 with Prime Factorization
| 2 | 390, 374, 916, 460, 308 |
| 2 | 195, 187, 458, 230, 154 |
| 5 | 195, 187, 229, 115, 77 |
| 11 | 39, 187, 229, 23, 77 |
| 39, 17, 229, 23, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 39 x 17 x 229 x 23 x 7 = 5377712340
Therefore, the lowest common multiple of 390,374,916,460,308 is 5377712340.
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.
390 x 374 x 916 x 460 x 308 = 18929547436800
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.
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
374 : 1, 2, 11, 17, 22, 34, 187, 374
916 : 1, 2, 4, 229, 458, 916
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,374,916,460,308, is 2.
Now, the common factors can be found like this.
390:2x 3x 5x 13
374:2x 11x 17
916:2x 2x 229
460:2x 2x 5x 23
308:2x 2x 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 2x 2x 5x 11 = 1760
Therefore, the value for common factors is 1760.
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 = 18929547436800/(2x1760)
LCM = 18929547436800/3520
LCM = 5377712340
Thus, we can understand that the LCM of 390,374,916,460,308 is 5377712340.
