Find LCM of 518,789,759,644,813 with Prime Factorization
2 | 518, 789, 759, 644, 813 |
3 | 259, 789, 759, 322, 813 |
7 | 259, 263, 253, 322, 271 |
23 | 37, 263, 253, 46, 271 |
37, 263, 11, 2, 271 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 37 x 263 x 11 x 2 x 271 = 56043670452
Therefore, the lowest common multiple of 518,789,759,644,813 is 56043670452.
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.
518 x 789 x 759 x 644 x 813 = 162414556969896
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.
518 : 1, 2, 7, 14, 37, 74, 259, 518
789 : 1, 3, 263, 789
759 : 1, 3, 11, 23, 33, 69, 253, 759
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
813 : 1, 3, 271, 813
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,789,759,644,813, is 1.
Now, the common factors can be found like this.
518:2x 7x 37
789:3x 263
759:3x 11x 23
644:2x 2x 7x 23
813:3x 271
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 3x 7x 23 = 2898
Therefore, the value for common factors is 2898.
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 = 162414556969896/(1x2898)
LCM = 162414556969896/2898
LCM = 56043670452
Thus, we can understand that the LCM of 518,789,759,644,813 is 56043670452.
