Given numbers are 299,900,780,345,247

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

The LCM of 299,900,780,345,247 is 5112900.

Find LCM of 299,900,780,345,247 with Prime Factorization

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

2 x 2 x 3 x 5 x 13 x 23 x 1 x 15 x 1 x 1 x 19 = 5112900

Therefore, the lowest common multiple of 299,900,780,345,247 is 5112900.

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.

299 x 900 x 780 x 345 x 247 = 17886458070000

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.

299 : 1, 13, 23, 299

900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

345 : 1, 3, 5, 15, 23, 69, 115, 345

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 299,900,780,345,247, is 1.

Now, the common factors can be found like this.

299:13x 23

900:2x 2x 3x 3x 5x 5

780:2x 2x 3x 5x 13

345:3x 5x 23

247:13x 19

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 3x 5x 5x 13x 13x 23 = 3498300

Therefore, the value for common factors is 3498300.

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 = 17886458070000/(1x3498300)

LCM = 17886458070000/3498300

LCM = 5112900

Thus, we can understand that the LCM of 299,900,780,345,247 is 5112900.
