Given numbers are 856,685,635,685

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

The LCM of 856,685,635,685 is 74467720.

Find LCM of 856,685,635,685 with Prime Factorization

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

5 x 137 x 856 x 1 x 127 x 1 = 74467720

Therefore, the lowest common multiple of 856,685,635,685 is 74467720.

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.

856 x 685 x 635 x 685 = 255051941000

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.

856 : 1, 2, 4, 8, 107, 214, 428, 856

685 : 1, 5, 137, 685

635 : 1, 5, 127, 635

685 : 1, 5, 137, 685

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,685,635,685, is 1.

Now, the common factors can be found like this.

856:2x 2x 2x 107

685:5x 137

635:5x 127

685:5x 137

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

5x 5x 137 = 3425

Therefore, the value for common factors is 3425.

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 = 255051941000/(1x3425)

LCM = 255051941000/3425

LCM = 74467720

Thus, we can understand that the LCM of 856,685,635,685 is 74467720.
