Given numbers are 205,209,695,655

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

The LCM of 205,209,695,655 is 780164605.

Find LCM of 205,209,695,655 with Prime Factorization

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

5 x 41 x 209 x 139 x 131 = 780164605

Therefore, the lowest common multiple of 205,209,695,655 is 780164605.

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.

205 x 209 x 695 x 655 = 19504115125

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.

205 : 1, 5, 41, 205

209 : 1, 11, 19, 209

695 : 1, 5, 139, 695

655 : 1, 5, 131, 655

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 205,209,695,655, is 1.

Now, the common factors can be found like this.

205:5x 41

209:11x 19

695:5x 139

655:5x 131

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 = 19504115125/(1x25)

LCM = 19504115125/25

LCM = 780164605

Thus, we can understand that the LCM of 205,209,695,655 is 780164605.
