Given numbers are 641,575,410,165

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

The LCM of 641,575,410,165 is 997363950.

Find LCM of 641,575,410,165 with Prime Factorization

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

5 x 641 x 115 x 82 x 33 = 997363950

Therefore, the lowest common multiple of 641,575,410,165 is 997363950.

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.

641 x 575 x 410 x 165 = 24934098750

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.

641 : 1, 641

575 : 1, 5, 23, 25, 115, 575

410 : 1, 2, 5, 10, 41, 82, 205, 410

165 : 1, 3, 5, 11, 15, 33, 55, 165

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,575,410,165, is 1.

Now, the common factors can be found like this.

641:641

575:5x 5x 23

410:2x 5x 41

165:3x 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.

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 24934098750/(1x25)

LCM = 24934098750/25

LCM = 997363950

Thus, we can understand that the LCM of 641,575,410,165 is 997363950.
