Given numbers are 805,103,874,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 805,103,874,689 is 2170880530.
Find LCM of 805,103,874,689 with Prime Factorization
23 | 805, 103, 874, 689 |
35, 103, 38, 689 |
Multiply the prime numbers at the bottom and the left side.
23 x 35 x 103 x 38 x 689 = 2170880530
Therefore, the lowest common multiple of 805,103,874,689 is 2170880530.
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.
805 x 103 x 874 x 689 = 49930252190
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
103 : 1, 103
874 : 1, 2, 19, 23, 38, 46, 437, 874
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,103,874,689, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
103:103
874:2x 19x 23
689:13x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23 = 23
Therefore, the value for common factors is 23.
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 = 49930252190/(1x23)
LCM = 49930252190/23
LCM = 2170880530
Thus, we can understand that the LCM of 805,103,874,689 is 2170880530.
