Given numbers are 194,728,353,100,780

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

The LCM of 194,728,353,100,780 is 1869558600.

Find LCM of 194,728,353,100,780 with Prime Factorization

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

2 x 2 x 5 x 13 x 97 x 14 x 353 x 5 x 3 = 1869558600

Therefore, the lowest common multiple of 194,728,353,100,780 is 1869558600.

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.

194 x 728 x 353 x 100 x 780 = 3888681888000

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.

194 : 1, 2, 97, 194

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

353 : 1, 353

100 : 1, 2, 4, 5, 10, 20, 25, 50, 100

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 194,728,353,100,780, is 1.

Now, the common factors can be found like this.

194:2x 97

728:2x 2x 2x 7x 13

353:353

100:2x 2x 5x 5

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 2x 2x 5x 13 = 2080

Therefore, the value for common factors is 2080.

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 = 3888681888000/(1x2080)

LCM = 3888681888000/2080

LCM = 1869558600

Thus, we can understand that the LCM of 194,728,353,100,780 is 1869558600.
