Given numbers are 685,507,649,286

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

The LCM of 685,507,649,286 is 450788910.

Find LCM of 685,507,649,286 with Prime Factorization

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

11 x 13 x 685 x 39 x 59 x 2 = 450788910

Therefore, the lowest common multiple of 685,507,649,286 is 450788910.

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.

685 x 507 x 649 x 286 = 64462814130

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.

685 : 1, 5, 137, 685

507 : 1, 3, 13, 39, 169, 507

649 : 1, 11, 59, 649

286 : 1, 2, 11, 13, 22, 26, 143, 286

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,507,649,286, is 1.

Now, the common factors can be found like this.

685:5x 137

507:3x 13x 13

649:11x 59

286:2x 11x 13

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

11x 13 = 143

Therefore, the value for common factors is 143.

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 = 64462814130/(1x143)

LCM = 64462814130/143

LCM = 450788910

Thus, we can understand that the LCM of 685,507,649,286 is 450788910.
