Given numbers are 738,686,451,451
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 738,686,451,451 is 2784474.
Find LCM of 738,686,451,451 with Prime Factorization
| 2 | 738, 686, 451, 451 |
| 11 | 369, 343, 451, 451 |
| 41 | 369, 343, 41, 41 |
| 9, 343, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 41 x 9 x 343 x 1 x 1 = 2784474
Therefore, the lowest common multiple of 738,686,451,451 is 2784474.
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.
738 x 686 x 451 x 451 = 102975417468
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.
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
686 : 1, 2, 7, 14, 49, 98, 343, 686
451 : 1, 11, 41, 451
451 : 1, 11, 41, 451
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 738,686,451,451, is 1.
Now, the common factors can be found like this.
738:2x 3x 3x 41
686:2x 7x 7x 7
451:11x 41
451:11x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 41x 41 = 36982
Therefore, the value for common factors is 36982.
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 = 102975417468/(1x36982)
LCM = 102975417468/36982
LCM = 2784474
Thus, we can understand that the LCM of 738,686,451,451 is 2784474.
