The LCM of 818,791,568,616 is 2021346712.
Find LCM of 818,791,568,616 with Prime Factorization
| 2 | 818, 791, 568, 616 |
| 2 | 409, 791, 284, 308 |
| 2 | 409, 791, 142, 154 |
| 7 | 409, 791, 71, 77 |
| 409, 113, 71, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 409 x 113 x 71 x 11 = 2021346712
Therefore, the lowest common multiple of 818,791,568,616 is 2021346712.
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.
818 x 791 x 568 x 616 = 226390831744
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.
818 : 1, 2, 409, 818
791 : 1, 7, 113, 791
568 : 1, 2, 4, 8, 71, 142, 284, 568
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,791,568,616, is 1.
Now, the common factors can be found like this.
818:2x 409
791:7x 113
568:2x 2x 2x 71
616:2x 2x 2x 7x 11
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 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 226390831744/(1x112)
LCM = 226390831744/112
LCM = 2021346712
Thus, we can understand that the LCM of 818,791,568,616 is 2021346712.
