Given numbers are 681,156,153,591

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

The LCM of 681,156,153,591 is 355784364.

Find LCM of 681,156,153,591 with Prime Factorization

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

3 x 227 x 52 x 51 x 197 = 355784364

Therefore, the lowest common multiple of 681,156,153,591 is 355784364.

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.

681 x 156 x 153 x 591 = 9606177828

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.

681 : 1, 3, 227, 681

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

153 : 1, 3, 9, 17, 51, 153

591 : 1, 3, 197, 591

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,156,153,591, is 3.

Now, the common factors can be found like this.

681:3x 227

156:2x 2x 3x 13

153:3x 3x 17

591:3x 197

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 9606177828/(3x9)

LCM = 9606177828/27

LCM = 355784364

Thus, we can understand that the LCM of 681,156,153,591 is 355784364.
