Given numbers are 403,618,728,464,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,618,728,464,494 is 7684810224.
Find LCM of 403,618,728,464,494 with Prime Factorization
| 2 | 403, 618, 728, 464, 494 |
| 2 | 403, 309, 364, 232, 247 |
| 2 | 403, 309, 182, 116, 247 |
| 13 | 403, 309, 91, 58, 247 |
| 31, 309, 7, 58, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 31 x 309 x 7 x 58 x 19 = 7684810224
Therefore, the lowest common multiple of 403,618,728,464,494 is 7684810224.
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.
403 x 618 x 728 x 464 x 494 = 41559453691392
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.
403 : 1, 13, 31, 403
618 : 1, 2, 3, 6, 103, 206, 309, 618
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,618,728,464,494, is 1.
Now, the common factors can be found like this.
403:13x 31
618:2x 3x 103
728:2x 2x 2x 7x 13
464:2x 2x 2x 2x 29
494:2x 13x 19
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 13x 13 = 5408
Therefore, the value for common factors is 5408.
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 = 41559453691392/(1x5408)
LCM = 41559453691392/5408
LCM = 7684810224
Thus, we can understand that the LCM of 403,618,728,464,494 is 7684810224.
