The LCM of 510,345,808,707,390 is 431241720.
Find LCM of 510,345,808,707,390 with Prime Factorization
| 2 | 510, 345, 808, 707, 390 |
| 3 | 255, 345, 404, 707, 195 |
| 5 | 85, 115, 404, 707, 65 |
| 101 | 17, 23, 404, 707, 13 |
| 17, 23, 4, 7, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 101 x 17 x 23 x 4 x 7 x 13 = 431241720
Therefore, the lowest common multiple of 510,345,808,707,390 is 431241720.
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.
510 x 345 x 808 x 707 x 390 = 39199872348000
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.
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
345 : 1, 3, 5, 15, 23, 69, 115, 345
808 : 1, 2, 4, 8, 101, 202, 404, 808
707 : 1, 7, 101, 707
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 510,345,808,707,390, is 1.
Now, the common factors can be found like this.
510:2x 3x 5x 17
345:3x 5x 23
808:2x 2x 2x 101
707:7x 101
390:2x 3x 5x 13
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 3x 3x 5x 5x 101 = 90900
Therefore, the value for common factors is 90900.
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 = 39199872348000/(1x90900)
LCM = 39199872348000/90900
LCM = 431241720
Thus, we can understand that the LCM of 510,345,808,707,390 is 431241720.
