Given numbers are 585,103,790,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 585,103,790,720 is 76162320.
Find LCM of 585,103,790,720 with Prime Factorization
| 2 | 585, 103, 790, 720 |
| 3 | 585, 103, 395, 360 |
| 3 | 195, 103, 395, 120 |
| 5 | 65, 103, 395, 40 |
| 13, 103, 79, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 13 x 103 x 79 x 8 = 76162320
Therefore, the lowest common multiple of 585,103,790,720 is 76162320.
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.
585 x 103 x 790 x 720 = 34273044000
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.
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
103 : 1, 103
790 : 1, 2, 5, 10, 79, 158, 395, 790
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 585,103,790,720, is 1.
Now, the common factors can be found like this.
585:3x 3x 5x 13
103:103
790:2x 5x 79
720:2x 2x 2x 2x 3x 3x 5
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 3x 5x 5 = 450
Therefore, the value for common factors is 450.
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 = 34273044000/(1x450)
LCM = 34273044000/450
LCM = 76162320
Thus, we can understand that the LCM of 585,103,790,720 is 76162320.
