Find LCM of 515,799,772,578,865 with Prime Factorization
| 2 | 515, 799, 772, 578, 865 |
| 5 | 515, 799, 386, 289, 865 |
| 17 | 103, 799, 386, 289, 173 |
| 103, 47, 386, 17, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 103 x 47 x 386 x 17 x 173 = 934256941220
Therefore, the lowest common multiple of 515,799,772,578,865 is 934256941220.
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.
515 x 799 x 772 x 578 x 865 = 158823680007400
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.
515 : 1, 5, 103, 515
799 : 1, 17, 47, 799
772 : 1, 2, 4, 193, 386, 772
578 : 1, 2, 17, 34, 289, 578
865 : 1, 5, 173, 865
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,799,772,578,865, is 1.
Now, the common factors can be found like this.
515:5x 103
799:17x 47
772:2x 2x 193
578:2x 17x 17
865:5x 173
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 17 = 170
Therefore, the value for common factors is 170.
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 = 158823680007400/(1x170)
LCM = 158823680007400/170
LCM = 934256941220
Thus, we can understand that the LCM of 515,799,772,578,865 is 934256941220.
