Find LCM of 638,810,531,628,197 with Prime Factorization
2 | 638, 810, 531, 628, 197 |
3 | 319, 405, 531, 314, 197 |
3 | 319, 135, 177, 314, 197 |
319, 45, 59, 314, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 319 x 45 x 59 x 314 x 197 = 943025828580
Therefore, the lowest common multiple of 638,810,531,628,197 is 943025828580.
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.
638 x 810 x 531 x 628 x 197 = 33948929828880
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
531 : 1, 3, 9, 59, 177, 531
628 : 1, 2, 4, 157, 314, 628
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,810,531,628,197, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
810:2x 3x 3x 3x 3x 5
531:3x 3x 59
628:2x 2x 157
197:197
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 33948929828880/(1x36)
LCM = 33948929828880/36
LCM = 943025828580
Thus, we can understand that the LCM of 638,810,531,628,197 is 943025828580.
