The LCM of 615,513,585,805,954 is 23331696570.
Find LCM of 615,513,585,805,954 with Prime Factorization
| 3 | 615, 513, 585, 805, 954 |
| 3 | 205, 171, 195, 805, 318 |
| 5 | 205, 57, 65, 805, 106 |
| 41, 57, 13, 161, 106 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 41 x 57 x 13 x 161 x 106 = 23331696570
Therefore, the lowest common multiple of 615,513,585,805,954 is 23331696570.
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.
615 x 513 x 585 x 805 x 954 = 141740056662750
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
513 : 1, 3, 9, 19, 27, 57, 171, 513
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
805 : 1, 5, 7, 23, 35, 115, 161, 805
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,513,585,805,954, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
513:3x 3x 3x 19
585:3x 3x 5x 13
805:5x 7x 23
954:2x 3x 3x 53
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 3x 3x 5x 5 = 6075
Therefore, the value for common factors is 6075.
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 = 141740056662750/(1x6075)
LCM = 141740056662750/6075
LCM = 23331696570
Thus, we can understand that the LCM of 615,513,585,805,954 is 23331696570.
