Given numbers are 381,728,247,197,653

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

The LCM of 381,728,247,197,653 is 677937040872.

Find LCM of 381,728,247,197,653 with Prime Factorization

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

13 x 381 x 56 x 19 x 197 x 653 = 677937040872

Therefore, the lowest common multiple of 381,728,247,197,653 is 677937040872.

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.

381 x 728 x 247 x 197 x 653 = 8813181531336

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.

381 : 1, 3, 127, 381

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

247 : 1, 13, 19, 247

197 : 1, 197

653 : 1, 653

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,728,247,197,653, is 1.

Now, the common factors can be found like this.

381:3x 127

728:2x 2x 2x 7x 13

247:13x 19

197:197

653:653

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

13 = 13

Therefore, the value for common factors is 13.

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 = 8813181531336/(1x13)

LCM = 8813181531336/13

LCM = 677937040872

Thus, we can understand that the LCM of 381,728,247,197,653 is 677937040872.
