Find LCM of 306,798,985,274,646 with Prime Factorization
| 2 | 306, 798, 985, 274, 646 |
| 3 | 153, 399, 985, 137, 323 |
| 17 | 51, 133, 985, 137, 323 |
| 19 | 3, 133, 985, 137, 19 |
| 3, 7, 985, 137, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 19 x 3 x 7 x 985 x 137 x 1 = 5491991610
Therefore, the lowest common multiple of 306,798,985,274,646 is 5491991610.
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.
306 x 798 x 985 x 274 x 646 = 42573918960720
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.
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
985 : 1, 5, 197, 985
274 : 1, 2, 137, 274
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 306,798,985,274,646, is 1.
Now, the common factors can be found like this.
306:2x 3x 3x 17
798:2x 3x 7x 19
985:5x 197
274:2x 137
646:2x 17x 19
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 3x 17x 19 = 7752
Therefore, the value for common factors is 7752.
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 = 42573918960720/(1x7752)
LCM = 42573918960720/7752
LCM = 5491991610
Thus, we can understand that the LCM of 306,798,985,274,646 is 5491991610.
