Given numbers are 939,648,400,841
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 939,648,400,841 is 8528749200.
Find LCM of 939,648,400,841 with Prime Factorization
| 2 | 939, 648, 400, 841 |
| 2 | 939, 324, 200, 841 |
| 2 | 939, 162, 100, 841 |
| 3 | 939, 81, 50, 841 |
| 313, 27, 50, 841 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 313 x 27 x 50 x 841 = 8528749200
Therefore, the lowest common multiple of 939,648,400,841 is 8528749200.
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.
939 x 648 x 400 x 841 = 204689980800
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.
939 : 1, 3, 313, 939
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
841 : 1, 29, 841
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 939,648,400,841, is 1.
Now, the common factors can be found like this.
939:3x 313
648:2x 2x 2x 3x 3x 3x 3
400:2x 2x 2x 2x 5x 5
841:29x 29
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 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 204689980800/(1x24)
LCM = 204689980800/24
LCM = 8528749200
Thus, we can understand that the LCM of 939,648,400,841 is 8528749200.
