Given numbers are 784,884,809,497
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,884,809,497 is 9952110896.
Find LCM of 784,884,809,497 with Prime Factorization
| 2 | 784, 884, 809, 497 |
| 2 | 392, 442, 809, 497 |
| 7 | 196, 221, 809, 497 |
| 28, 221, 809, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 28 x 221 x 809 x 71 = 9952110896
Therefore, the lowest common multiple of 784,884,809,497 is 9952110896.
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.
784 x 884 x 809 x 497 = 278659105088
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
809 : 1, 809
497 : 1, 7, 71, 497
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,884,809,497, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
884:2x 2x 13x 17
809:809
497:7x 71
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 7 = 28
Therefore, the value for common factors is 28.
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 = 278659105088/(1x28)
LCM = 278659105088/28
LCM = 9952110896
Thus, we can understand that the LCM of 784,884,809,497 is 9952110896.
