The LCM of 306,549,663,617 is 149719986.
Find LCM of 306,549,663,617 with Prime Factorization
| 3 | 306, 549, 663, 617 |
| 3 | 102, 183, 221, 617 |
| 17 | 34, 61, 221, 617 |
| 2, 61, 13, 617 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 17 x 2 x 61 x 13 x 617 = 149719986
Therefore, the lowest common multiple of 306,549,663,617 is 149719986.
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 549 x 663 x 617 = 68721473574
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
549 : 1, 3, 9, 61, 183, 549
663 : 1, 3, 13, 17, 39, 51, 221, 663
617 : 1, 617
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 306,549,663,617, is 1.
Now, the common factors can be found like this.
306:2x 3x 3x 17
549:3x 3x 61
663:3x 13x 17
617:617
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 17 = 459
Therefore, the value for common factors is 459.
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 = 68721473574/(1x459)
LCM = 68721473574/459
LCM = 149719986
Thus, we can understand that the LCM of 306,549,663,617 is 149719986.
