Given numbers are 166,702,154,720,689

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

The LCM of 166,702,154,720,689 is 9511341840.

Find LCM of 166,702,154,720,689 with Prime Factorization

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

2 x 3 x 3 x 13 x 83 x 3 x 77 x 40 x 53 = 9511341840

Therefore, the lowest common multiple of 166,702,154,720,689 is 9511341840.

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.

166 x 702 x 154 x 720 x 689 = 8902615962240

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.

166 : 1, 2, 83, 166

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

154 : 1, 2, 7, 11, 14, 22, 77, 154

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 166,702,154,720,689, is 1.

Now, the common factors can be found like this.

166:2x 83

702:2x 3x 3x 3x 13

154:2x 7x 11

720:2x 2x 2x 2x 3x 3x 5

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.

2x 2x 2x 3x 3x 13 = 936

Therefore, the value for common factors is 936.

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 = 8902615962240/(1x936)

LCM = 8902615962240/936

LCM = 9511341840

Thus, we can understand that the LCM of 166,702,154,720,689 is 9511341840.
