Find LCM of 640,584,835,391,797 with Prime Factorization
2 | 640, 584, 835, 391, 797 |
2 | 320, 292, 835, 391, 797 |
2 | 160, 146, 835, 391, 797 |
5 | 80, 73, 835, 391, 797 |
16, 73, 167, 391, 797 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 16 x 73 x 167 x 391 x 797 = 2431388644480
Therefore, the lowest common multiple of 640,584,835,391,797 is 2431388644480.
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.
640 x 584 x 835 x 391 x 797 = 97255545779200
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
584 : 1, 2, 4, 8, 73, 146, 292, 584
835 : 1, 5, 167, 835
391 : 1, 17, 23, 391
797 : 1, 797
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,584,835,391,797, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
584:2x 2x 2x 73
835:5x 167
391:17x 23
797:797
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 = 97255545779200/(1x40)
LCM = 97255545779200/40
LCM = 2431388644480
Thus, we can understand that the LCM of 640,584,835,391,797 is 2431388644480.
