Given numbers are 685,805,274,985

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

The LCM of 685,805,274,985 is 43452290.

Find LCM of 685,805,274,985 with Prime Factorization

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

5 x 137 x 1 x 161 x 2 x 197 = 43452290

Therefore, the lowest common multiple of 685,805,274,985 is 43452290.

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 805 x 274 x 985 = 148824093250

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

805 : 1, 5, 7, 23, 35, 115, 161, 805

274 : 1, 2, 137, 274

985 : 1, 5, 197, 985

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,805,274,985, is 1.

Now, the common factors can be found like this.

685:5x 137

805:5x 7x 23

274:2x 137

985:5x 197

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

5x 5x 137 = 3425

Therefore, the value for common factors is 3425.

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 = 148824093250/(1x3425)

LCM = 148824093250/3425

LCM = 43452290

Thus, we can understand that the LCM of 685,805,274,985 is 43452290.
