Given numbers are 820,257,623,494,534

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

The LCM of 820,257,623,494,534 is 97286645820.

Find LCM of 820,257,623,494,534 with Prime Factorization

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

2 x 89 x 410 x 257 x 7 x 247 x 3 = 97286645820

Therefore, the lowest common multiple of 820,257,623,494,534 is 97286645820.

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 257 x 623 x 494 x 534 = 34634045911920

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

257 : 1, 257

623 : 1, 7, 89, 623

494 : 1, 2, 13, 19, 26, 38, 247, 494

534 : 1, 2, 3, 6, 89, 178, 267, 534

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,257,623,494,534, is 1.

Now, the common factors can be found like this.

820:2x 2x 5x 41

257:257

623:7x 89

494:2x 13x 19

534:2x 3x 89

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 89 = 356

Therefore, the value for common factors is 356.

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 = 34634045911920/(1x356)

LCM = 34634045911920/356

LCM = 97286645820

Thus, we can understand that the LCM of 820,257,623,494,534 is 97286645820.
