Given numbers are 839,812,790,939,745
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 839,812,790,939,745 is 37650170423460.
Find LCM of 839,812,790,939,745 with Prime Factorization
| 2 | 839, 812, 790, 939, 745 |
| 5 | 839, 406, 395, 939, 745 |
| 839, 406, 79, 939, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 839 x 406 x 79 x 939 x 149 = 37650170423460
Therefore, the lowest common multiple of 839,812,790,939,745 is 37650170423460.
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.
839 x 812 x 790 x 939 x 745 = 376501704234600
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.
839 : 1, 839
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
790 : 1, 2, 5, 10, 79, 158, 395, 790
939 : 1, 3, 313, 939
745 : 1, 5, 149, 745
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 839,812,790,939,745, is 1.
Now, the common factors can be found like this.
839:839
812:2x 2x 7x 29
790:2x 5x 79
939:3x 313
745:5x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 376501704234600/(1x10)
LCM = 376501704234600/10
LCM = 37650170423460
Thus, we can understand that the LCM of 839,812,790,939,745 is 37650170423460.
