Given numbers are 196,193,256,841

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

The LCM of 196,193,256,841 is 2036054272.

Find LCM of 196,193,256,841 with Prime Factorization

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

2 x 2 x 49 x 193 x 64 x 841 = 2036054272

Therefore, the lowest common multiple of 196,193,256,841 is 2036054272.

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.

196 x 193 x 256 x 841 = 8144217088

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.

196 : 1, 2, 4, 7, 14, 28, 49, 98, 196

193 : 1, 193

256 : 1, 2, 4, 8, 16, 32, 64, 128, 256

841 : 1, 29, 841

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 196,193,256,841, is 1.

Now, the common factors can be found like this.

196:2x 2x 7x 7

193:193

256:2x 2x 2x 2x 2x 2x 2x 2

841:29x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 8144217088/(1x4)

LCM = 8144217088/4

LCM = 2036054272

Thus, we can understand that the LCM of 196,193,256,841 is 2036054272.
