Given numbers are 326,640,556,710
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 326,640,556,710 is 1029534080.
Find LCM of 326,640,556,710 with Prime Factorization
| 2 | 326, 640, 556, 710 |
| 2 | 163, 320, 278, 355 |
| 5 | 163, 160, 139, 355 |
| 163, 32, 139, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 163 x 32 x 139 x 71 = 1029534080
Therefore, the lowest common multiple of 326,640,556,710 is 1029534080.
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.
326 x 640 x 556 x 710 = 82362726400
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.
326 : 1, 2, 163, 326
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
556 : 1, 2, 4, 139, 278, 556
710 : 1, 2, 5, 10, 71, 142, 355, 710
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 326,640,556,710, is 2.
Now, the common factors can be found like this.
326:2x 163
640:2x 2x 2x 2x 2x 2x 2x 5
556:2x 2x 139
710:2x 5x 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 2x 2x 5 = 40
Therefore, the value for common factors is 40.
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 = 82362726400/(2x40)
LCM = 82362726400/80
LCM = 1029534080
Thus, we can understand that the LCM of 326,640,556,710 is 1029534080.
