Given numbers are 685,155,412,554

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

The LCM of 685,155,412,554 is 2423423140.

Find LCM of 685,155,412,554 with Prime Factorization

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

2 x 5 x 137 x 31 x 206 x 277 = 2423423140

Therefore, the lowest common multiple of 685,155,412,554 is 2423423140.

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 155 x 412 x 554 = 24234231400

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

155 : 1, 5, 31, 155

412 : 1, 2, 4, 103, 206, 412

554 : 1, 2, 277, 554

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,155,412,554, is 1.

Now, the common factors can be found like this.

685:5x 137

155:5x 31

412:2x 2x 103

554:2x 277

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 24234231400/(1x10)

LCM = 24234231400/10

LCM = 2423423140

Thus, we can understand that the LCM of 685,155,412,554 is 2423423140.
