Given numbers are 421,862,256,448,194

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

The LCM of 421,862,256,448,194 is 31540538624.

Find LCM of 421,862,256,448,194 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 2 x 421 x 431 x 4 x 7 x 97 = 31540538624

Therefore, the lowest common multiple of 421,862,256,448,194 is 31540538624.

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.

421 x 862 x 256 x 448 x 194 = 8074377887744

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.

421 : 1, 421

862 : 1, 2, 431, 862

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

448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448

194 : 1, 2, 97, 194

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,862,256,448,194, is 1.

Now, the common factors can be found like this.

421:421

862:2x 431

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

448:2x 2x 2x 2x 2x 2x 7

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 2x 2x 2x 2 = 256

Therefore, the value for common factors is 256.

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 = 8074377887744/(1x256)

LCM = 8074377887744/256

LCM = 31540538624

Thus, we can understand that the LCM of 421,862,256,448,194 is 31540538624.
