Given numbers are 685,251,653,985,487

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

The LCM of 685,251,653,985,487 is 10771412593145.

Find LCM of 685,251,653,985,487 with Prime Factorization

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

5 x 137 x 251 x 653 x 197 x 487 = 10771412593145

Therefore, the lowest common multiple of 685,251,653,985,487 is 10771412593145.

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 251 x 653 x 985 x 487 = 53857062965725

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

251 : 1, 251

653 : 1, 653

985 : 1, 5, 197, 985

487 : 1, 487

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,251,653,985,487, is 1.

Now, the common factors can be found like this.

685:5x 137

251:251

653:653

985:5x 197

487:487

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

5 = 5

Therefore, the value for common factors is 5.

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 = 53857062965725/(1x5)

LCM = 53857062965725/5

LCM = 10771412593145

Thus, we can understand that the LCM of 685,251,653,985,487 is 10771412593145.
