Find LCM of 619,206,309,845,945 with Prime Factorization
3 | 619, 206, 309, 845, 945 |
5 | 619, 206, 103, 845, 315 |
103 | 619, 206, 103, 169, 63 |
619, 2, 1, 169, 63 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 103 x 619 x 2 x 1 x 169 x 63 = 20364623370
Therefore, the lowest common multiple of 619,206,309,845,945 is 20364623370.
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.
619 x 206 x 309 x 845 x 945 = 31463343106650
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.
619 : 1, 619
206 : 1, 2, 103, 206
309 : 1, 3, 103, 309
845 : 1, 5, 13, 65, 169, 845
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,206,309,845,945, is 1.
Now, the common factors can be found like this.
619:619
206:2x 103
309:3x 103
845:5x 13x 13
945:3x 3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 103 = 1545
Therefore, the value for common factors is 1545.
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 = 31463343106650/(1x1545)
LCM = 31463343106650/1545
LCM = 20364623370
Thus, we can understand that the LCM of 619,206,309,845,945 is 20364623370.
