Given numbers are 798,308,836,830
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 798,308,836,830 is 7285740.
Find LCM of 798,308,836,830 with Prime Factorization
| 2 | 798, 308, 836, 830 |
| 2 | 399, 154, 418, 415 |
| 7 | 399, 77, 209, 415 |
| 11 | 57, 11, 209, 415 |
| 19 | 57, 1, 19, 415 |
| 3, 1, 1, 415 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 19 x 3 x 1 x 1 x 415 = 7285740
Therefore, the lowest common multiple of 798,308,836,830 is 7285740.
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.
798 x 308 x 836 x 830 = 170544601920
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.
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
830 : 1, 2, 5, 10, 83, 166, 415, 830
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,308,836,830, is 2.
Now, the common factors can be found like this.
798:2x 3x 7x 19
308:2x 2x 7x 11
836:2x 2x 11x 19
830:2x 5x 83
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 7x 11x 19 = 11704
Therefore, the value for common factors is 11704.
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 = 170544601920/(2x11704)
LCM = 170544601920/23408
LCM = 7285740
Thus, we can understand that the LCM of 798,308,836,830 is 7285740.
