Given numbers are 637,468,561,585,393
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 637,468,561,585,393 is 2808826020.
Find LCM of 637,468,561,585,393 with Prime Factorization
| 3 | 637, 468, 561, 585, 393 |
| 3 | 637, 156, 187, 195, 131 |
| 13 | 637, 52, 187, 65, 131 |
| 49, 4, 187, 5, 131 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 13 x 49 x 4 x 187 x 5 x 131 = 2808826020
Therefore, the lowest common multiple of 637,468,561,585,393 is 2808826020.
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.
637 x 468 x 561 x 585 x 393 = 38450019387780
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.
637 : 1, 7, 13, 49, 91, 637
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
561 : 1, 3, 11, 17, 33, 51, 187, 561
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
393 : 1, 3, 131, 393
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,468,561,585,393, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
468:2x 2x 3x 3x 13
561:3x 11x 17
585:3x 3x 5x 13
393:3x 131
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 3x 3x 13x 13 = 13689
Therefore, the value for common factors is 13689.
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 = 38450019387780/(1x13689)
LCM = 38450019387780/13689
LCM = 2808826020
Thus, we can understand that the LCM of 637,468,561,585,393 is 2808826020.
