Given numbers are 194,720,570,515

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

The LCM of 194,720,570,515 is 136676880.

Find LCM of 194,720,570,515 with Prime Factorization

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

2 x 3 x 5 x 97 x 24 x 19 x 103 = 136676880

Therefore, the lowest common multiple of 194,720,570,515 is 136676880.

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.

194 x 720 x 570 x 515 = 41003064000

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.

194 : 1, 2, 97, 194

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570

515 : 1, 5, 103, 515

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 194,720,570,515, is 1.

Now, the common factors can be found like this.

194:2x 97

720:2x 2x 2x 2x 3x 3x 5

570:2x 3x 5x 19

515:5x 103

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

2x 2x 3x 5x 5 = 300

Therefore, the value for common factors is 300.

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 = 41003064000/(1x300)

LCM = 41003064000/300

LCM = 136676880

Thus, we can understand that the LCM of 194,720,570,515 is 136676880.

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