Given numbers are 780,201,858,194,556

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

The LCM of 780,201,858,194,556 is 7750837380.

Find LCM of 780,201,858,194,556 with Prime Factorization

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

2 x 2 x 3 x 13 x 5 x 67 x 11 x 97 x 139 = 7750837380

Therefore, the lowest common multiple of 780,201,858,194,556 is 7750837380.

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.

780 x 201 x 858 x 194 x 556 = 14509567575360

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.

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

201 : 1, 3, 67, 201

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

194 : 1, 2, 97, 194

556 : 1, 2, 4, 139, 278, 556

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,201,858,194,556, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

201:3x 67

858:2x 3x 11x 13

194:2x 97

556:2x 2x 139

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 2x 3x 3x 13 = 1872

Therefore, the value for common factors is 1872.

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 = 14509567575360/(1x1872)

LCM = 14509567575360/1872

LCM = 7750837380

Thus, we can understand that the LCM of 780,201,858,194,556 is 7750837380.
