Given numbers are 641,991,608,266,291

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

The LCM of 641,991,608,266,291 is 786731052576.

Find LCM of 641,991,608,266,291 with Prime Factorization

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

2 x 19 x 641 x 991 x 16 x 7 x 291 = 786731052576

Therefore, the lowest common multiple of 641,991,608,266,291 is 786731052576.

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 991 x 608 x 266 x 291 = 29895779997888

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

991 : 1, 991

608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608

266 : 1, 2, 7, 14, 19, 38, 133, 266

291 : 1, 3, 97, 291

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,991,608,266,291, is 1.

Now, the common factors can be found like this.

641:641

991:991

608:2x 2x 2x 2x 2x 19

266:2x 7x 19

291:3x 97

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

2x 19 = 38

Therefore, the value for common factors is 38.

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 = 29895779997888/(1x38)

LCM = 29895779997888/38

LCM = 786731052576

Thus, we can understand that the LCM of 641,991,608,266,291 is 786731052576.
