Given numbers are 820,698,942,263,553

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

The LCM of 820,698,942,263,553 is 19603836252420.

Find LCM of 820,698,942,263,553 with Prime Factorization

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

2 x 410 x 349 x 471 x 263 x 553 = 19603836252420

Therefore, the lowest common multiple of 820,698,942,263,553 is 19603836252420.

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 698 x 942 x 263 x 553 = 78415345009680

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

698 : 1, 2, 349, 698

942 : 1, 2, 3, 6, 157, 314, 471, 942

263 : 1, 263

553 : 1, 7, 79, 553

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,698,942,263,553, is 1.

Now, the common factors can be found like this.

820:2x 2x 5x 41

698:2x 349

942:2x 3x 157

263:263

553:7x 79

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 = 78415345009680/(1x4)

LCM = 78415345009680/4

LCM = 19603836252420

Thus, we can understand that the LCM of 820,698,942,263,553 is 19603836252420.
