Given numbers are 403,494,856
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,494,856 is 6554392.
Find LCM of 403,494,856 with Prime Factorization
| 2 | 403, 494, 856 |
| 13 | 403, 247, 428 |
| 31, 19, 428 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 31 x 19 x 428 = 6554392
Therefore, the lowest common multiple of 403,494,856 is 6554392.
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 494 x 856 = 170414192
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
494 : 1, 2, 13, 19, 26, 38, 247, 494
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,494,856, is 1.
Now, the common factors can be found like this.
403:13x 31
494:2x 13x 19
856:2x 2x 2x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 170414192/(1x26)
LCM = 170414192/26
LCM = 6554392
Thus, we can understand that the LCM of 403,494,856 is 6554392.
