Given numbers are 193,865,138,140

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

The LCM of 193,865,138,140 is 322537740.

Find LCM of 193,865,138,140 with Prime Factorization

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

2 x 5 x 193 x 173 x 69 x 14 = 322537740

Therefore, the lowest common multiple of 193,865,138,140 is 322537740.

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 865 x 138 x 140 = 3225377400

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

865 : 1, 5, 173, 865

138 : 1, 2, 3, 6, 23, 46, 69, 138

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 193,865,138,140, is 1.

Now, the common factors can be found like this.

193:193

865:5x 173

138:2x 3x 23

140:2x 2x 5x 7

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 = 3225377400/(1x10)

LCM = 3225377400/10

LCM = 322537740

Thus, we can understand that the LCM of 193,865,138,140 is 322537740.
