Given numbers are 497,287,387,695,315
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 497,287,387,695,315 is 5480699805.
Find LCM of 497,287,387,695,315 with Prime Factorization
| 3 | 497, 287, 387, 695, 315 |
| 3 | 497, 287, 129, 695, 105 |
| 5 | 497, 287, 43, 695, 35 |
| 7 | 497, 287, 43, 139, 7 |
| 71, 41, 43, 139, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 71 x 41 x 43 x 139 x 1 = 5480699805
Therefore, the lowest common multiple of 497,287,387,695,315 is 5480699805.
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.
497 x 287 x 387 x 695 x 315 = 12084943070025
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.
497 : 1, 7, 71, 497
287 : 1, 7, 41, 287
387 : 1, 3, 9, 43, 129, 387
695 : 1, 5, 139, 695
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 497,287,387,695,315, is 1.
Now, the common factors can be found like this.
497:7x 71
287:7x 41
387:3x 3x 43
695:5x 139
315:3x 3x 5x 7
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 7x 7 = 2205
Therefore, the value for common factors is 2205.
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 = 12084943070025/(1x2205)
LCM = 12084943070025/2205
LCM = 5480699805
Thus, we can understand that the LCM of 497,287,387,695,315 is 5480699805.
