Given numbers are 820,803,686,274

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

The LCM of 820,803,686,274 is 30941693860.

Find LCM of 820,803,686,274 with Prime Factorization

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

2 x 410 x 803 x 343 x 137 = 30941693860

Therefore, the lowest common multiple of 820,803,686,274 is 30941693860.

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 803 x 686 x 274 = 123766775440

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

803 : 1, 11, 73, 803

686 : 1, 2, 7, 14, 49, 98, 343, 686

274 : 1, 2, 137, 274

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,803,686,274, is 1.

Now, the common factors can be found like this.

820:2x 2x 5x 41

803:11x 73

686:2x 7x 7x 7

274:2x 137

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 123766775440/(1x4)

LCM = 123766775440/4

LCM = 30941693860

Thus, we can understand that the LCM of 820,803,686,274 is 30941693860.
