Given numbers are 778,471,622,757
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,471,622,757 is 86269399026.
Find LCM of 778,471,622,757 with Prime Factorization
| 2 | 778, 471, 622, 757 |
| 389, 471, 311, 757 |
Multiply the prime numbers at the bottom and the left side.
2 x 389 x 471 x 311 x 757 = 86269399026
Therefore, the lowest common multiple of 778,471,622,757 is 86269399026.
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.
778 x 471 x 622 x 757 = 172538798052
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.
778 : 1, 2, 389, 778
471 : 1, 3, 157, 471
622 : 1, 2, 311, 622
757 : 1, 757
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,471,622,757, is 1.
Now, the common factors can be found like this.
778:2x 389
471:3x 157
622:2x 311
757:757
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 172538798052/(1x2)
LCM = 172538798052/2
LCM = 86269399026
Thus, we can understand that the LCM of 778,471,622,757 is 86269399026.
