Given numbers are 685,137,648

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

The LCM of 685,137,648 is 443880.

Find LCM of 685,137,648 with Prime Factorization

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

137 x 5 x 1 x 648 = 443880

Therefore, the lowest common multiple of 685,137,648 is 443880.

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 137 x 648 = 60811560

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

137 : 1, 137

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,137,648, is 1.

Now, the common factors can be found like this.

685:5x 137

137:137

648:2x 2x 2x 3x 3x 3x 3

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

137 = 137

Therefore, the value for common factors is 137.

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 = 60811560/(1x137)

LCM = 60811560/137

LCM = 443880

Thus, we can understand that the LCM of 685,137,648 is 443880.

Here are some samples of LCM of two or more Numbers calculations.
