Calculate the LCM of 843,689,761,684,161

Given numbers are 843,689,761,684,161

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 843,689,761,684,161 is 16225279109676.

Find LCM of 843,689,761,684,161 with Prime Factorization


3 843, 689, 761, 684, 161
281, 689, 761, 228, 161

Multiply the prime numbers at the bottom and the left side.

3 x 281 x 689 x 761 x 228 x 161 = 16225279109676

Therefore, the lowest common multiple of 843,689,761,684,161 is 16225279109676.

LCM Formula to Find Lowest Common Multiple of 843,689,761,684,161

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.

843 x 689 x 761 x 684 x 161 = 48675837329028

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.

843 : 1, 3, 281, 843

689 : 1, 13, 53, 689

761 : 1, 761

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,689,761,684,161, is 1.

Now, the common factors can be found like this.

843:3x 281

689:13x 53

761:761

684:2x 2x 3x 3x 19

161:7x 23

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3 = 3

Therefore, the value for common factors is 3.

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 = 48675837329028/(1x3)

LCM = 48675837329028/3

LCM = 16225279109676

Thus, we can understand that the LCM of 843,689,761,684,161 is 16225279109676.
