Given numbers are 646,681,482,655

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

The LCM of 646,681,482,655 is 69444518730.

Find LCM of 646,681,482,655 with Prime Factorization

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

2 x 323 x 681 x 241 x 655 = 69444518730

Therefore, the lowest common multiple of 646,681,482,655 is 69444518730.

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.

646 x 681 x 482 x 655 = 138889037460

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

681 : 1, 3, 227, 681

482 : 1, 2, 241, 482

655 : 1, 5, 131, 655

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,681,482,655, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

681:3x 227

482:2x 241

655:5x 131

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 = 138889037460/(1x2)

LCM = 138889037460/2

LCM = 69444518730

Thus, we can understand that the LCM of 646,681,482,655 is 69444518730.
