Given numbers are 630,493,261,215
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 630,493,261,215 is 13355370.
Find LCM of 630,493,261,215 with Prime Factorization
| 3 | 630, 493, 261, 215 |
| 3 | 210, 493, 87, 215 |
| 5 | 70, 493, 29, 215 |
| 29 | 14, 493, 29, 43 |
| 14, 17, 1, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 29 x 14 x 17 x 1 x 43 = 13355370
Therefore, the lowest common multiple of 630,493,261,215 is 13355370.
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 493 x 261 x 215 = 17428757850
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
493 : 1, 17, 29, 493
261 : 1, 3, 9, 29, 87, 261
215 : 1, 5, 43, 215
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,493,261,215, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
493:17x 29
261:3x 3x 29
215:5x 43
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 5x 29 = 1305
Therefore, the value for common factors is 1305.
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 = 17428757850/(1x1305)
LCM = 17428757850/1305
LCM = 13355370
Thus, we can understand that the LCM of 630,493,261,215 is 13355370.
