Given numbers are 394,226,452,821

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

The LCM of 394,226,452,821 is 73105124.

Find LCM of 394,226,452,821 with Prime Factorization

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

2 x 113 x 197 x 1 x 2 x 821 = 73105124

Therefore, the lowest common multiple of 394,226,452,821 is 73105124.

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.

394 x 226 x 452 x 821 = 33043516048

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.

394 : 1, 2, 197, 394

226 : 1, 2, 113, 226

452 : 1, 2, 4, 113, 226, 452

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,226,452,821, is 1.

Now, the common factors can be found like this.

394:2x 197

226:2x 113

452:2x 2x 113

821:821

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 113 = 452

Therefore, the value for common factors is 452.

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 = 33043516048/(1x452)

LCM = 33043516048/452

LCM = 73105124

Thus, we can understand that the LCM of 394,226,452,821 is 73105124.
