Given numbers are 751,108,682,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 751,108,682,639 is 1963705788.
Find LCM of 751,108,682,639 with Prime Factorization
| 2 | 751, 108, 682, 639 |
| 3 | 751, 54, 341, 639 |
| 3 | 751, 18, 341, 213 |
| 751, 6, 341, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 751 x 6 x 341 x 71 = 1963705788
Therefore, the lowest common multiple of 751,108,682,639 is 1963705788.
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.
751 x 108 x 682 x 639 = 35346704184
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.
751 : 1, 751
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
682 : 1, 2, 11, 22, 31, 62, 341, 682
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 751,108,682,639, is 1.
Now, the common factors can be found like this.
751:751
108:2x 2x 3x 3x 3
682:2x 11x 31
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 35346704184/(1x18)
LCM = 35346704184/18
LCM = 1963705788
Thus, we can understand that the LCM of 751,108,682,639 is 1963705788.
