Given numbers are 593,646,561,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 593,646,561,638 is 366605646.
Find LCM of 593,646,561,638 with Prime Factorization
| 2 | 593, 646, 561, 638 |
| 11 | 593, 323, 561, 319 |
| 17 | 593, 323, 51, 29 |
| 593, 19, 3, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 593 x 19 x 3 x 29 = 366605646
Therefore, the lowest common multiple of 593,646,561,638 is 366605646.
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.
593 x 646 x 561 x 638 = 137110511604
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.
593 : 1, 593
646 : 1, 2, 17, 19, 34, 38, 323, 646
561 : 1, 3, 11, 17, 33, 51, 187, 561
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 593,646,561,638, is 1.
Now, the common factors can be found like this.
593:593
646:2x 17x 19
561:3x 11x 17
638:2x 11x 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 11x 17 = 374
Therefore, the value for common factors is 374.
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 = 137110511604/(1x374)
LCM = 137110511604/374
LCM = 366605646
Thus, we can understand that the LCM of 593,646,561,638 is 366605646.
