Given numbers are 208,197,728,203

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

The LCM of 208,197,728,203 is 8318128.

Find LCM of 208,197,728,203 with Prime Factorization

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

2 x 2 x 2 x 7 x 13 x 2 x 197 x 1 x 29 = 8318128

Therefore, the lowest common multiple of 208,197,728,203 is 8318128.

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 197 x 728 x 203 = 6055597184

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

197 : 1, 197

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

203 : 1, 7, 29, 203

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 208,197,728,203, is 1.

Now, the common factors can be found like this.

208:2x 2x 2x 2x 13

197:197

728:2x 2x 2x 7x 13

203:7x 29

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 7x 13 = 728

Therefore, the value for common factors is 728.

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 = 6055597184/(1x728)

LCM = 6055597184/728

LCM = 8318128

Thus, we can understand that the LCM of 208,197,728,203 is 8318128.
