Given numbers are 621,169,806,291
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 621,169,806,291 is 631163286.
Find LCM of 621,169,806,291 with Prime Factorization
3 | 621, 169, 806, 291 |
13 | 207, 169, 806, 97 |
207, 13, 62, 97 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 207 x 13 x 62 x 97 = 631163286
Therefore, the lowest common multiple of 621,169,806,291 is 631163286.
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.
621 x 169 x 806 x 291 = 24615368154
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
169 : 1, 13, 169
806 : 1, 2, 13, 26, 31, 62, 403, 806
291 : 1, 3, 97, 291
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,169,806,291, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
169:13x 13
806:2x 13x 31
291:3x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13 = 39
Therefore, the value for common factors is 39.
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 = 24615368154/(1x39)
LCM = 24615368154/39
LCM = 631163286
Thus, we can understand that the LCM of 621,169,806,291 is 631163286.
