Given numbers are 689,837,439,854,909
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,837,439,854,909 is 21836772251658.
Find LCM of 689,837,439,854,909 with Prime Factorization
3 | 689, 837, 439, 854, 909 |
3 | 689, 279, 439, 854, 303 |
689, 93, 439, 854, 101 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 689 x 93 x 439 x 854 x 101 = 21836772251658
Therefore, the lowest common multiple of 689,837,439,854,909 is 21836772251658.
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.
689 x 837 x 439 x 854 x 909 = 196530950264922
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.
689 : 1, 13, 53, 689
837 : 1, 3, 9, 27, 31, 93, 279, 837
439 : 1, 439
854 : 1, 2, 7, 14, 61, 122, 427, 854
909 : 1, 3, 9, 101, 303, 909
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,837,439,854,909, is 1.
Now, the common factors can be found like this.
689:13x 53
837:3x 3x 3x 31
439:439
854:2x 7x 61
909:3x 3x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 196530950264922/(1x9)
LCM = 196530950264922/9
LCM = 21836772251658
Thus, we can understand that the LCM of 689,837,439,854,909 is 21836772251658.
