Given numbers are 738,694,861,432
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 738,694,861,432 is 43022448.
Find LCM of 738,694,861,432 with Prime Factorization
| 2 | 738, 694, 861, 432 |
| 3 | 369, 347, 861, 216 |
| 3 | 123, 347, 287, 72 |
| 41 | 41, 347, 287, 24 |
| 1, 347, 7, 24 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 41 x 1 x 347 x 7 x 24 = 43022448
Therefore, the lowest common multiple of 738,694,861,432 is 43022448.
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 694 x 861 x 432 = 190503399744
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
694 : 1, 2, 347, 694
861 : 1, 3, 7, 21, 41, 123, 287, 861
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 738,694,861,432, is 1.
Now, the common factors can be found like this.
738:2x 3x 3x 41
694:2x 347
861:3x 7x 41
432:2x 2x 2x 2x 3x 3x 3
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 3x 3x 3x 41 = 4428
Therefore, the value for common factors is 4428.
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 = 190503399744/(1x4428)
LCM = 190503399744/4428
LCM = 43022448
Thus, we can understand that the LCM of 738,694,861,432 is 43022448.
