Given numbers are 878,812,732,798
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 878,812,732,798 is 1239439236.
Find LCM of 878,812,732,798 with Prime Factorization
| 2 | 878, 812, 732, 798 |
| 2 | 439, 406, 366, 399 |
| 3 | 439, 203, 183, 399 |
| 7 | 439, 203, 61, 133 |
| 439, 29, 61, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 439 x 29 x 61 x 19 = 1239439236
Therefore, the lowest common multiple of 878,812,732,798 is 1239439236.
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.
878 x 812 x 732 x 798 = 416451583296
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.
878 : 1, 2, 439, 878
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 878,812,732,798, is 2.
Now, the common factors can be found like this.
878:2x 439
812:2x 2x 7x 29
732:2x 2x 3x 61
798:2x 3x 7x 19
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 416451583296/(2x168)
LCM = 416451583296/336
LCM = 1239439236
Thus, we can understand that the LCM of 878,812,732,798 is 1239439236.
