Given numbers are 820,422,454,713

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

The LCM of 820,422,454,713 is 28003460020.

Find LCM of 820,422,454,713 with Prime Factorization

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

2 x 410 x 211 x 227 x 713 = 28003460020

Therefore, the lowest common multiple of 820,422,454,713 is 28003460020.

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 422 x 454 x 713 = 112013840080

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

422 : 1, 2, 211, 422

454 : 1, 2, 227, 454

713 : 1, 23, 31, 713

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,422,454,713, is 1.

Now, the common factors can be found like this.

820:2x 2x 5x 41

422:2x 211

454:2x 227

713:23x 31

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 = 112013840080/(1x4)

LCM = 112013840080/4

LCM = 28003460020

Thus, we can understand that the LCM of 820,422,454,713 is 28003460020.
