Given numbers are 418,494,398,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,494,398,961 is 1039192726.
Find LCM of 418,494,398,961 with Prime Factorization
| 2 | 418, 494, 398, 961 |
| 19 | 209, 247, 199, 961 |
| 11, 13, 199, 961 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 11 x 13 x 199 x 961 = 1039192726
Therefore, the lowest common multiple of 418,494,398,961 is 1039192726.
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.
418 x 494 x 398 x 961 = 78978647176
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
494 : 1, 2, 13, 19, 26, 38, 247, 494
398 : 1, 2, 199, 398
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,494,398,961, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
494:2x 13x 19
398:2x 199
961:31x 31
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 19 = 76
Therefore, the value for common factors is 76.
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 = 78978647176/(1x76)
LCM = 78978647176/76
LCM = 1039192726
Thus, we can understand that the LCM of 418,494,398,961 is 1039192726.
