Given numbers are 784,808,483,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,808,483,870 is 792235920.
Find LCM of 784,808,483,870 with Prime Factorization
| 2 | 784, 808, 483, 870 |
| 2 | 392, 404, 483, 435 |
| 2 | 196, 202, 483, 435 |
| 3 | 98, 101, 483, 435 |
| 7 | 98, 101, 161, 145 |
| 14, 101, 23, 145 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 14 x 101 x 23 x 145 = 792235920
Therefore, the lowest common multiple of 784,808,483,870 is 792235920.
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 808 x 483 x 870 = 266191269120
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
808 : 1, 2, 4, 8, 101, 202, 404, 808
483 : 1, 3, 7, 21, 23, 69, 161, 483
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,808,483,870, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
808:2x 2x 2x 101
483:3x 7x 23
870:2x 3x 5x 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 2x 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 266191269120/(1x336)
LCM = 266191269120/336
LCM = 792235920
Thus, we can understand that the LCM of 784,808,483,870 is 792235920.
