Given numbers are 338,913,902,179,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 338,913,902,179,642 is 726991608486.
Find LCM of 338,913,902,179,642 with Prime Factorization
| 2 | 338, 913, 902, 179, 642 |
| 11 | 169, 913, 451, 179, 321 |
| 169, 83, 41, 179, 321 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 169 x 83 x 41 x 179 x 321 = 726991608486
Therefore, the lowest common multiple of 338,913,902,179,642 is 726991608486.
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 913 x 902 x 179 x 642 = 31987630773384
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
913 : 1, 11, 83, 913
902 : 1, 2, 11, 22, 41, 82, 451, 902
179 : 1, 179
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,913,902,179,642, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
913:11x 83
902:2x 11x 41
179:179
642:2x 3x 107
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 11 = 44
Therefore, the value for common factors is 44.
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 = 31987630773384/(1x44)
LCM = 31987630773384/44
LCM = 726991608486
Thus, we can understand that the LCM of 338,913,902,179,642 is 726991608486.
