Given numbers are 193,646,137,685

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

The LCM of 193,646,137,685 is 85404430.

Find LCM of 193,646,137,685 with Prime Factorization

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

137 x 193 x 646 x 1 x 5 = 85404430

Therefore, the lowest common multiple of 193,646,137,685 is 85404430.

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.

193 x 646 x 137 x 685 = 11700406910

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.

193 : 1, 193

646 : 1, 2, 17, 19, 34, 38, 323, 646

137 : 1, 137

685 : 1, 5, 137, 685

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 193,646,137,685, is 1.

Now, the common factors can be found like this.

193:193

646:2x 17x 19

137:137

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.

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 = 11700406910/(1x137)

LCM = 11700406910/137

LCM = 85404430

Thus, we can understand that the LCM of 193,646,137,685 is 85404430.
