Given numbers are 858,206,312,780

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

The LCM of 858,206,312,780 is 1767480.

Find LCM of 858,206,312,780 with Prime Factorization

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

2 x 2 x 3 x 13 x 11 x 103 x 2 x 5 = 1767480

Therefore, the lowest common multiple of 858,206,312,780 is 1767480.

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.

858 x 206 x 312 x 780 = 43013393280

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.

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

206 : 1, 2, 103, 206

312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,206,312,780, is 2.

Now, the common factors can be found like this.

858:2x 3x 11x 13

206:2x 103

312:2x 2x 2x 3x 13

780:2x 2x 3x 5x 13

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 2x 3x 3x 13x 13 = 12168

Therefore, the value for common factors is 12168.

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 = 43013393280/(2x12168)

LCM = 43013393280/24336

LCM = 1767480

Thus, we can understand that the LCM of 858,206,312,780 is 1767480.
