Given numbers are 771,163,721,939
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 771,163,721,939 is 28361002929.
Find LCM of 771,163,721,939 with Prime Factorization
| 3 | 771, 163, 721, 939 |
| 257, 163, 721, 313 |
Multiply the prime numbers at the bottom and the left side.
3 x 257 x 163 x 721 x 313 = 28361002929
Therefore, the lowest common multiple of 771,163,721,939 is 28361002929.
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.
771 x 163 x 721 x 939 = 85083008787
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.
771 : 1, 3, 257, 771
163 : 1, 163
721 : 1, 7, 103, 721
939 : 1, 3, 313, 939
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,163,721,939, is 1.
Now, the common factors can be found like this.
771:3x 257
163:163
721:7x 103
939:3x 313
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 85083008787/(1x3)
LCM = 85083008787/3
LCM = 28361002929
Thus, we can understand that the LCM of 771,163,721,939 is 28361002929.
