Given numbers are 785,386,820,354

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

The LCM of 785,386,820,354 is 4397887140.

Find LCM of 785,386,820,354 with Prime Factorization

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

2 x 5 x 157 x 193 x 82 x 177 = 4397887140

Therefore, the lowest common multiple of 785,386,820,354 is 4397887140.

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.

785 x 386 x 820 x 354 = 87957742800

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.

785 : 1, 5, 157, 785

386 : 1, 2, 193, 386

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

354 : 1, 2, 3, 6, 59, 118, 177, 354

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,386,820,354, is 1.

Now, the common factors can be found like this.

785:5x 157

386:2x 193

820:2x 2x 5x 41

354:2x 3x 59

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 5 = 20

Therefore, the value for common factors is 20.

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 = 87957742800/(1x20)

LCM = 87957742800/20

LCM = 4397887140

Thus, we can understand that the LCM of 785,386,820,354 is 4397887140.
