Given numbers are 820,386,685,337

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

The LCM of 820,386,685,337 is 7306705940.

Find LCM of 820,386,685,337 with Prime Factorization

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

2 x 5 x 82 x 193 x 137 x 337 = 7306705940

Therefore, the lowest common multiple of 820,386,685,337 is 7306705940.

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.

820 x 386 x 685 x 337 = 73067059400

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.

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

386 : 1, 2, 193, 386

685 : 1, 5, 137, 685

337 : 1, 337

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,386,685,337, is 1.

Now, the common factors can be found like this.

820:2x 2x 5x 41

386:2x 193

685:5x 137

337:337

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 73067059400/(1x10)

LCM = 73067059400/10

LCM = 7306705940

Thus, we can understand that the LCM of 820,386,685,337 is 7306705940.
