Given numbers are 854,920,394

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

The LCM of 854,920,394 is 77389480.

Find LCM of 854,920,394 with Prime Factorization

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

2 x 427 x 460 x 197 = 77389480

Therefore, the lowest common multiple of 854,920,394 is 77389480.

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.

854 x 920 x 394 = 309557920

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.

854 : 1, 2, 7, 14, 61, 122, 427, 854

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

394 : 1, 2, 197, 394

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 854,920,394, is 2.

Now, the common factors can be found like this.

854:2x 7x 61

920:2x 2x 2x 5x 23

394:2x 197

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 = 309557920/(2x2)

LCM = 309557920/4

LCM = 77389480

Thus, we can understand that the LCM of 854,920,394 is 77389480.
