Given numbers are 325,556,988,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 325,556,988,782 is 1342420300.
Find LCM of 325,556,988,782 with Prime Factorization
| 2 | 325, 556, 988, 782 |
| 2 | 325, 278, 494, 391 |
| 13 | 325, 139, 247, 391 |
| 25, 139, 19, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 25 x 139 x 19 x 391 = 1342420300
Therefore, the lowest common multiple of 325,556,988,782 is 1342420300.
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.
325 x 556 x 988 x 782 = 139611711200
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.
325 : 1, 5, 13, 25, 65, 325
556 : 1, 2, 4, 139, 278, 556
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 325,556,988,782, is 1.
Now, the common factors can be found like this.
325:5x 5x 13
556:2x 2x 139
988:2x 2x 13x 19
782:2x 17x 23
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 2x 13 = 104
Therefore, the value for common factors is 104.
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 = 139611711200/(1x104)
LCM = 139611711200/104
LCM = 1342420300
Thus, we can understand that the LCM of 325,556,988,782 is 1342420300.
