Find LCM of 518,391,629,561,345 with Prime Factorization
| 3 | 518, 391, 629, 561, 345 |
| 17 | 518, 391, 629, 187, 115 |
| 23 | 518, 23, 37, 11, 115 |
| 37 | 518, 1, 37, 11, 5 |
| 14, 1, 1, 11, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 23 x 37 x 14 x 1 x 1 x 11 x 5 = 33418770
Therefore, the lowest common multiple of 518,391,629,561,345 is 33418770.
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 391 x 629 x 561 x 345 = 24656936625090
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
391 : 1, 17, 23, 391
629 : 1, 17, 37, 629
561 : 1, 3, 11, 17, 33, 51, 187, 561
345 : 1, 3, 5, 15, 23, 69, 115, 345
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,391,629,561,345, is 1.
Now, the common factors can be found like this.
518:2x 7x 37
391:17x 23
629:17x 37
561:3x 11x 17
345:3x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17x 17x 23x 37 = 737817
Therefore, the value for common factors is 737817.
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 = 24656936625090/(1x737817)
LCM = 24656936625090/737817
LCM = 33418770
Thus, we can understand that the LCM of 518,391,629,561,345 is 33418770.
