Find LCM of 630,818,790,522,870 with Prime Factorization
| 2 | 630, 818, 790, 522, 870 |
| 3 | 315, 409, 395, 261, 435 |
| 3 | 105, 409, 395, 87, 145 |
| 5 | 35, 409, 395, 29, 145 |
| 29 | 7, 409, 79, 29, 29 |
| 7, 409, 79, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 29 x 7 x 409 x 79 x 1 x 1 = 590321970
Therefore, the lowest common multiple of 630,818,790,522,870 is 590321970.
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.
630 x 818 x 790 x 522 x 870 = 184888841004000
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.
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
818 : 1, 2, 409, 818
790 : 1, 2, 5, 10, 79, 158, 395, 790
522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,818,790,522,870, is 2.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
818:2x 409
790:2x 5x 79
522:2x 3x 3x 29
870:2x 3x 5x 29
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 2x 3x 3x 3x 5x 5x 29 = 156600
Therefore, the value for common factors is 156600.
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 = 184888841004000/(2x156600)
LCM = 184888841004000/313200
LCM = 590321970
Thus, we can understand that the LCM of 630,818,790,522,870 is 590321970.
