Given numbers are 338,798,703,380
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 338,798,703,380 is 49898940.
Find LCM of 338,798,703,380 with Prime Factorization
| 2 | 338, 798, 703, 380 |
| 19 | 169, 399, 703, 190 |
| 169, 21, 37, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 169 x 21 x 37 x 10 = 49898940
Therefore, the lowest common multiple of 338,798,703,380 is 49898940.
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.
338 x 798 x 703 x 380 = 72054069360
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.
338 : 1, 2, 13, 26, 169, 338
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
703 : 1, 19, 37, 703
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,798,703,380, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
798:2x 3x 7x 19
703:19x 37
380:2x 2x 5x 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 19x 19 = 1444
Therefore, the value for common factors is 1444.
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 = 72054069360/(1x1444)
LCM = 72054069360/1444
LCM = 49898940
Thus, we can understand that the LCM of 338,798,703,380 is 49898940.
