Given numbers are 539,785,355,690,420

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

The LCM of 539,785,355,690,420 is 8291361540.

Find LCM of 539,785,355,690,420 with Prime Factorization

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

2 x 3 x 5 x 7 x 77 x 157 x 71 x 23 x 2 = 8291361540

Therefore, the lowest common multiple of 539,785,355,690,420 is 8291361540.

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.

539 x 785 x 355 x 690 x 420 = 43529648085000

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.

539 : 1, 7, 11, 49, 77, 539

785 : 1, 5, 157, 785

355 : 1, 5, 71, 355

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 539,785,355,690,420, is 1.

Now, the common factors can be found like this.

539:7x 7x 11

785:5x 157

355:5x 71

690:2x 3x 5x 23

420:2x 2x 3x 5x 7

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

2x 3x 5x 5x 5x 7 = 5250

Therefore, the value for common factors is 5250.

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 = 43529648085000/(1x5250)

LCM = 43529648085000/5250

LCM = 8291361540

Thus, we can understand that the LCM of 539,785,355,690,420 is 8291361540.
