Given numbers are 645,617,806,802,188
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 645,617,806,802,188 is 12090719524260.
Find LCM of 645,617,806,802,188 with Prime Factorization
2 | 645, 617, 806, 802, 188 |
645, 617, 403, 401, 94 |
Multiply the prime numbers at the bottom and the left side.
2 x 645 x 617 x 403 x 401 x 94 = 12090719524260
Therefore, the lowest common multiple of 645,617,806,802,188 is 12090719524260.
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.
645 x 617 x 806 x 802 x 188 = 48362878097040
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.
645 : 1, 3, 5, 15, 43, 129, 215, 645
617 : 1, 617
806 : 1, 2, 13, 26, 31, 62, 403, 806
802 : 1, 2, 401, 802
188 : 1, 2, 4, 47, 94, 188
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,617,806,802,188, is 1.
Now, the common factors can be found like this.
645:3x 5x 43
617:617
806:2x 13x 31
802:2x 401
188:2x 2x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 48362878097040/(1x4)
LCM = 48362878097040/4
LCM = 12090719524260
Thus, we can understand that the LCM of 645,617,806,802,188 is 12090719524260.
