Given numbers are 208,647,156,138,194

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

The LCM of 208,647,156,138,194 is 900717168.

Find LCM of 208,647,156,138,194 with Prime Factorization

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

2 x 2 x 3 x 13 x 4 x 647 x 1 x 23 x 97 = 900717168

Therefore, the lowest common multiple of 208,647,156,138,194 is 900717168.

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.

208 x 647 x 156 x 138 x 194 = 562047512832

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.

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

647 : 1, 647

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

194 : 1, 2, 97, 194

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 208,647,156,138,194, is 1.

Now, the common factors can be found like this.

208:2x 2x 2x 2x 13

647:647

156:2x 2x 3x 13

138:2x 3x 23

194:2x 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 2x 2x 2x 3x 13 = 624

Therefore, the value for common factors is 624.

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 = 562047512832/(1x624)

LCM = 562047512832/624

LCM = 900717168

Thus, we can understand that the LCM of 208,647,156,138,194 is 900717168.
