Find LCM of 618,847,986,509,561 with Prime Factorization
| 2 | 618, 847, 986, 509, 561 |
| 3 | 309, 847, 493, 509, 561 |
| 11 | 103, 847, 493, 509, 187 |
| 17 | 103, 77, 493, 509, 17 |
| 103, 77, 29, 509, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 17 x 103 x 77 x 29 x 509 x 1 = 131351968902
Therefore, the lowest common multiple of 618,847,986,509,561 is 131351968902.
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.
618 x 847 x 986 x 509 x 561 = 147376909108044
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.
618 : 1, 2, 3, 6, 103, 206, 309, 618
847 : 1, 7, 11, 77, 121, 847
986 : 1, 2, 17, 29, 34, 58, 493, 986
509 : 1, 509
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,847,986,509,561, is 1.
Now, the common factors can be found like this.
618:2x 3x 103
847:7x 11x 11
986:2x 17x 29
509:509
561:3x 11x 17
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 11x 17 = 1122
Therefore, the value for common factors is 1122.
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 = 147376909108044/(1x1122)
LCM = 147376909108044/1122
LCM = 131351968902
Thus, we can understand that the LCM of 618,847,986,509,561 is 131351968902.
