Given numbers are 338,227,923,780,847
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 338,227,923,780,847 is 138422143860.
Find LCM of 338,227,923,780,847 with Prime Factorization
| 2 | 338, 227, 923, 780, 847 |
| 13 | 169, 227, 923, 390, 847 |
| 13, 227, 71, 30, 847 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 13 x 227 x 71 x 30 x 847 = 138422143860
Therefore, the lowest common multiple of 338,227,923,780,847 is 138422143860.
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 227 x 923 x 780 x 847 = 46786684624680
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
227 : 1, 227
923 : 1, 13, 71, 923
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,227,923,780,847, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
227:227
923:13x 71
780:2x 2x 3x 5x 13
847:7x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 13 = 338
Therefore, the value for common factors is 338.
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 = 46786684624680/(1x338)
LCM = 46786684624680/338
LCM = 138422143860
Thus, we can understand that the LCM of 338,227,923,780,847 is 138422143860.
