Given numbers are 817,819,539,128,762

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

The LCM of 817,819,539,128,762 is 837549288576.

Find LCM of 817,819,539,128,762 with Prime Factorization

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

2 x 3 x 7 x 817 x 39 x 77 x 64 x 127 = 837549288576

Therefore, the lowest common multiple of 817,819,539,128,762 is 837549288576.

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.

817 x 819 x 539 x 128 x 762 = 35177070120192

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.

817 : 1, 19, 43, 817

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

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

128 : 1, 2, 4, 8, 16, 32, 64, 128

762 : 1, 2, 3, 6, 127, 254, 381, 762

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,819,539,128,762, is 1.

Now, the common factors can be found like this.

817:19x 43

819:3x 3x 7x 13

539:7x 7x 11

128:2x 2x 2x 2x 2x 2x 2

762:2x 3x 127

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 7 = 42

Therefore, the value for common factors is 42.

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 = 35177070120192/(1x42)

LCM = 35177070120192/42

LCM = 837549288576

Thus, we can understand that the LCM of 817,819,539,128,762 is 837549288576.
