Given numbers are 611,989,689,809
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 611,989,689,809 is 25909670683.
Find LCM of 611,989,689,809 with Prime Factorization
13 | 611, 989, 689, 809 |
47, 989, 53, 809 |
Multiply the prime numbers at the bottom and the left side.
13 x 47 x 989 x 53 x 809 = 25909670683
Therefore, the lowest common multiple of 611,989,689,809 is 25909670683.
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.
611 x 989 x 689 x 809 = 336825718879
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.
611 : 1, 13, 47, 611
989 : 1, 23, 43, 989
689 : 1, 13, 53, 689
809 : 1, 809
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 611,989,689,809, is 1.
Now, the common factors can be found like this.
611:13x 47
989:23x 43
689:13x 53
809:809
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 336825718879/(1x13)
LCM = 336825718879/13
LCM = 25909670683
Thus, we can understand that the LCM of 611,989,689,809 is 25909670683.
