Given numbers are 460,916,390,338
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 460,916,390,338 is 53407380.
Find LCM of 460,916,390,338 with Prime Factorization
| 2 | 460, 916, 390, 338 |
| 2 | 230, 458, 195, 169 |
| 5 | 115, 229, 195, 169 |
| 13 | 23, 229, 39, 169 |
| 23, 229, 3, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 23 x 229 x 3 x 13 = 53407380
Therefore, the lowest common multiple of 460,916,390,338 is 53407380.
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.
460 x 916 x 390 x 338 = 55543675200
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.
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
916 : 1, 2, 4, 229, 458, 916
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
338 : 1, 2, 13, 26, 169, 338
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 460,916,390,338, is 2.
Now, the common factors can be found like this.
460:2x 2x 5x 23
916:2x 2x 229
390:2x 3x 5x 13
338:2x 13x 13
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 5x 13 = 520
Therefore, the value for common factors is 520.
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 = 55543675200/(2x520)
LCM = 55543675200/1040
LCM = 53407380
Thus, we can understand that the LCM of 460,916,390,338 is 53407380.
