Given numbers are 286,273,745,780

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

The LCM of 286,273,745,780 is 8948940.

Find LCM of 286,273,745,780 with Prime Factorization

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

2 x 3 x 5 x 13 x 11 x 7 x 149 x 2 = 8948940

Therefore, the lowest common multiple of 286,273,745,780 is 8948940.

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.

286 x 273 x 745 x 780 = 45371125800

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.

286 : 1, 2, 11, 13, 22, 26, 143, 286

273 : 1, 3, 7, 13, 21, 39, 91, 273

745 : 1, 5, 149, 745

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,273,745,780, is 1.

Now, the common factors can be found like this.

286:2x 11x 13

273:3x 7x 13

745:5x 149

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 3x 5x 13x 13 = 5070

Therefore, the value for common factors is 5070.

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 = 45371125800/(1x5070)

LCM = 45371125800/5070

LCM = 8948940

Thus, we can understand that the LCM of 286,273,745,780 is 8948940.
