Given numbers are 779,904,306,731,749
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 779,904,306,731,749 is 3470144760936.
Find LCM of 779,904,306,731,749 with Prime Factorization
| 2 | 779, 904, 306, 731, 749 |
| 17 | 779, 452, 153, 731, 749 |
| 779, 452, 9, 43, 749 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 779 x 452 x 9 x 43 x 749 = 3470144760936
Therefore, the lowest common multiple of 779,904,306,731,749 is 3470144760936.
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.
779 x 904 x 306 x 731 x 749 = 117984921871824
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.
779 : 1, 19, 41, 779
904 : 1, 2, 4, 8, 113, 226, 452, 904
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
731 : 1, 17, 43, 731
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,904,306,731,749, is 1.
Now, the common factors can be found like this.
779:19x 41
904:2x 2x 2x 113
306:2x 3x 3x 17
731:17x 43
749:7x 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 17 = 34
Therefore, the value for common factors is 34.
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 = 117984921871824/(1x34)
LCM = 117984921871824/34
LCM = 3470144760936
Thus, we can understand that the LCM of 779,904,306,731,749 is 3470144760936.
