Given numbers are 394,478,895,821

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

The LCM of 394,478,895,821 is 69192705970.

Find LCM of 394,478,895,821 with Prime Factorization

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

2 x 197 x 239 x 895 x 821 = 69192705970

Therefore, the lowest common multiple of 394,478,895,821 is 69192705970.

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 478 x 895 x 821 = 138385411940

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

478 : 1, 2, 239, 478

895 : 1, 5, 179, 895

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,478,895,821, is 1.

Now, the common factors can be found like this.

394:2x 197

478:2x 239

895:5x 179

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 138385411940/(1x2)

LCM = 138385411940/2

LCM = 69192705970

Thus, we can understand that the LCM of 394,478,895,821 is 69192705970.
