Given numbers are 209,668,365,861,147

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

The LCM of 209,668,365,861,147 is 307126156260.

Find LCM of 209,668,365,861,147 with Prime Factorization

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

3 x 7 x 209 x 668 x 365 x 41 x 7 = 307126156260

Therefore, the lowest common multiple of 209,668,365,861,147 is 307126156260.

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.

209 x 668 x 365 x 861 x 147 = 6449649281460

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.

209 : 1, 11, 19, 209

668 : 1, 2, 4, 167, 334, 668

365 : 1, 5, 73, 365

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

147 : 1, 3, 7, 21, 49, 147

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,668,365,861,147, is 1.

Now, the common factors can be found like this.

209:11x 19

668:2x 2x 167

365:5x 73

861:3x 7x 41

147:3x 7x 7

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 6449649281460/(1x21)

LCM = 6449649281460/21

LCM = 307126156260

Thus, we can understand that the LCM of 209,668,365,861,147 is 307126156260.
