Given numbers are 209,660,793,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 209,660,793,989 is 9834833580.
Find LCM of 209,660,793,989 with Prime Factorization
11 | 209, 660, 793, 989 |
19, 60, 793, 989 |
Multiply the prime numbers at the bottom and the left side.
11 x 19 x 60 x 793 x 989 = 9834833580
Therefore, the lowest common multiple of 209,660,793,989 is 9834833580.
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.
209 x 660 x 793 x 989 = 108183169380
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.
209 : 1, 11, 19, 209
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
793 : 1, 13, 61, 793
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,660,793,989, is 1.
Now, the common factors can be found like this.
209:11x 19
660:2x 2x 3x 5x 11
793:13x 61
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 108183169380/(1x11)
LCM = 108183169380/11
LCM = 9834833580
Thus, we can understand that the LCM of 209,660,793,989 is 9834833580.
