Given numbers are 127,680,138,305

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

The LCM of 127,680,138,305 is 363489240.

Find LCM of 127,680,138,305 with Prime Factorization

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

2 x 5 x 127 x 68 x 69 x 61 = 363489240

Therefore, the lowest common multiple of 127,680,138,305 is 363489240.

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.

127 x 680 x 138 x 305 = 3634892400

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.

127 : 1, 127

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

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

305 : 1, 5, 61, 305

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 127,680,138,305, is 1.

Now, the common factors can be found like this.

127:127

680:2x 2x 2x 5x 17

138:2x 3x 23

305:5x 61

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 = 3634892400/(1x10)

LCM = 3634892400/10

LCM = 363489240

Thus, we can understand that the LCM of 127,680,138,305 is 363489240.

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