Given numbers are 645,861,297,682,825

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

The LCM of 645,861,297,682,825 is 5681179350.

Find LCM of 645,861,297,682,825 with Prime Factorization

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

3 x 5 x 11 x 43 x 287 x 9 x 62 x 5 = 5681179350

Therefore, the lowest common multiple of 645,861,297,682,825 is 5681179350.

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.

645 x 861 x 297 x 682 x 825 = 92802064682250

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

861 : 1, 3, 7, 21, 41, 123, 287, 861

297 : 1, 3, 9, 11, 27, 33, 99, 297

682 : 1, 2, 11, 22, 31, 62, 341, 682

825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,861,297,682,825, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

861:3x 7x 41

297:3x 3x 3x 11

682:2x 11x 31

825:3x 5x 5x 11

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

3x 3x 3x 5x 11x 11 = 16335

Therefore, the value for common factors is 16335.

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 = 92802064682250/(1x16335)

LCM = 92802064682250/16335

LCM = 5681179350

Thus, we can understand that the LCM of 645,861,297,682,825 is 5681179350.
