Given numbers are 613,489,685,685

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

The LCM of 613,489,685,685 is 205333545.

Find LCM of 613,489,685,685 with Prime Factorization

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

5 x 137 x 613 x 489 x 1 x 1 = 205333545

Therefore, the lowest common multiple of 613,489,685,685 is 205333545.

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.

613 x 489 x 685 x 685 = 140653478325

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.

613 : 1, 613

489 : 1, 3, 163, 489

685 : 1, 5, 137, 685

685 : 1, 5, 137, 685

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 613,489,685,685, is 1.

Now, the common factors can be found like this.

613:613

489:3x 163

685:5x 137

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 137 = 685

Therefore, the value for common factors is 685.

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 = 140653478325/(1x685)

LCM = 140653478325/685

LCM = 205333545

Thus, we can understand that the LCM of 613,489,685,685 is 205333545.
