Given numbers are 689,143,406,156

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

The LCM of 689,143,406,156 is 18462444.

Find LCM of 689,143,406,156 with Prime Factorization

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

2 x 13 x 53 x 11 x 203 x 6 = 18462444

Therefore, the lowest common multiple of 689,143,406,156 is 18462444.

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 143 x 406 x 156 = 6240306072

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

143 : 1, 11, 13, 143

406 : 1, 2, 7, 14, 29, 58, 203, 406

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,143,406,156, is 1.

Now, the common factors can be found like this.

689:13x 53

143:11x 13

406:2x 7x 29

156:2x 2x 3x 13

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

2x 13x 13 = 338

Therefore, the value for common factors is 338.

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 = 6240306072/(1x338)

LCM = 6240306072/338

LCM = 18462444

Thus, we can understand that the LCM of 689,143,406,156 is 18462444.
