Given numbers are 721,349,381,198
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,349,381,198 is 6327462834.
Find LCM of 721,349,381,198 with Prime Factorization
| 3 | 721, 349, 381, 198 |
| 721, 349, 127, 66 |
Multiply the prime numbers at the bottom and the left side.
3 x 721 x 349 x 127 x 66 = 6327462834
Therefore, the lowest common multiple of 721,349,381,198 is 6327462834.
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.
721 x 349 x 381 x 198 = 18982388502
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.
721 : 1, 7, 103, 721
349 : 1, 349
381 : 1, 3, 127, 381
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,349,381,198, is 1.
Now, the common factors can be found like this.
721:7x 103
349:349
381:3x 127
198:2x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 18982388502/(1x3)
LCM = 18982388502/3
LCM = 6327462834
Thus, we can understand that the LCM of 721,349,381,198 is 6327462834.
