Given numbers are 847,780,858,486

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

The LCM of 847,780,858,486 is 53513460.

Find LCM of 847,780,858,486 with Prime Factorization

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

2 x 3 x 11 x 13 x 77 x 10 x 1 x 81 = 53513460

Therefore, the lowest common multiple of 847,780,858,486 is 53513460.

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.

847 x 780 x 858 x 486 = 275487292080

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.

847 : 1, 7, 11, 77, 121, 847

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

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

486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,780,858,486, is 1.

Now, the common factors can be found like this.

847:7x 11x 11

780:2x 2x 3x 5x 13

858:2x 3x 11x 13

486:2x 3x 3x 3x 3x 3

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 11x 13 = 5148

Therefore, the value for common factors is 5148.

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 = 275487292080/(1x5148)

LCM = 275487292080/5148

LCM = 53513460

Thus, we can understand that the LCM of 847,780,858,486 is 53513460.
