Given numbers are 1,666,856,785

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

The LCM of 1,666,856,785 is 223762680.

Find LCM of 1,666,856,785 with Prime Factorization

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

2 x 1 x 333 x 428 x 785 = 223762680

Therefore, the lowest common multiple of 1,666,856,785 is 223762680.

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.

1 x 666 x 856 x 785 = 447525360

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.

1 : 1

666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666

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

785 : 1, 5, 157, 785

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,666,856,785, is 1.

Now, the common factors can be found like this.

1:

666:2x 3x 3x 37

856:2x 2x 2x 107

785:5x 157

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

2 = 2

Therefore, the value for common factors is 2.

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 = 447525360/(1x2)

LCM = 447525360/2

LCM = 223762680

Thus, we can understand that the LCM of 1,666,856,785 is 223762680.
