Given numbers are 209,878,103,309

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

The LCM of 209,878,103,309 is 56702118.

Find LCM of 209,878,103,309 with Prime Factorization

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

103 x 209 x 878 x 1 x 3 = 56702118

Therefore, the lowest common multiple of 209,878,103,309 is 56702118.

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 878 x 103 x 309 = 5840318154

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

878 : 1, 2, 439, 878

103 : 1, 103

309 : 1, 3, 103, 309

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,878,103,309, is 1.

Now, the common factors can be found like this.

209:11x 19

878:2x 439

103:103

309:3x 103

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

103 = 103

Therefore, the value for common factors is 103.

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 = 5840318154/(1x103)

LCM = 5840318154/103

LCM = 56702118

Thus, we can understand that the LCM of 209,878,103,309 is 56702118.
